  • Deciphering genetic susceptibility to frontotemporal lobar dementia
    - Nature genetics 42(3):189-190 (2010)
    A genome-wide association study has identified a new genetic susceptibility factor for a subtype of frontotemporal lobar dementia characterized by TDP-43 inclusions. The work illustrates how high-quality phenotyping can increase power to detect risk alleles for rare heterogeneous diseases.
  • Open chromatin and diabetes risk
    - Nature genetics 42(3):190-192 (2010)
    A new study has identified a large number of open chromatin regions harboring active regulatory elements in human pancreatic islets. A type 2 diabetes–associated SNP in TCF7L2 was found to be located in a region of allele-specific open chromatin and shows allele-specific enhancer activity, suggesting a potential mechanism for this disease association.
  • Understanding variable expressivity in microdeletion syndromes
    - Nature genetics 42(3):192-193 (2010)
    A new study reports an elevated frequency of second-site genomic alterations among children with severe developmental delay who carry a recurrent microdeletion at chromosome 16p12.1. The work highlights the complex relationship between genotype and phenotype and provides a model to explain the clinical variability associated with this and other common microdeletion syndromes.

We identified an association with telomere length on 3q26 (rs12696304, combined P = 3.72 × 10−14) at a locus that includes TERC, which encodes the telomerase RNA component. Each copy of the minor allele of rs12696304 was associated with an ~75-base-pair reduction in mean telomere length, equivalent to ~3.6 years of age-related telomere-length attrition.

of a recurrent, 520-kb 16p12.1 microdeletion associated with childhood developmental delay. The microdeletion was detected in 20 of 11,873 cases compared with 2 of 8,540 controls (P = 0.0009, OR = 7.2) and replicated in a second series of 22 of 9,254 cases compared with 6 of 6,299 controls (P = 0.028, OR = 2.5). Most deletions were inherited, with carrier parents likely to manifest neuropsychiatric phenotypes compared to non-carrier parents (P = 0.037, OR = 6). Probands were more likely to carry an additional large copy-number variant when compared to matched controls (10 of 42 cases, P = 5.7 × 10−5, OR = 6.6). The clinical features of individuals with two mutations were distinct from and/or more severe than those of individuals carrying only the co-occurring mutation. Our data support a two-hit model in which the 16p12.1 microdeletion both predisposes to neuropsychiatric phenotypes as a single event and exacerbates neurodevelopmental phenotyp! es in association with other large deletions or duplications. Analysis of other microdeletions with variable expressivity indicates that this two-hit model might be more generally applicable to neuropsychiatric disease. View full text Figures at a glance * Figure 1: High-resolution array-based CGH characterization of 16p12.1 microdeletion. Shown is validation of 16p12.1 microdeletions in a representative set of cases using high-resolution tiling-path custom array-based CGH. Probes with log2 ratios above or below a threshold of 1.5 s.d. from the normalized mean log2 ratio are colored green (duplication) or red (deletion), respectively. Dotted lines represent breakpoint regions. Subjects SG01–13 and SGA3–7 have indications of developmental delay or cognitive disability, sample 43163 is from the GAIN schizophrenia study and subject LD1205-03 has schizophrenia and intellectual disability (from family LD1205). Note that samples 26140 and 18125 were analyzed as part of the GAIN control cohort for schizophrenia. It is noteworthy that one control (subject 26140) was retrospectively diagnosed with a major depressive disorder. Six RefSeq genes map within the 16p12.1 microdeletion. Four subjects (SG04, SG07, SG11 (affected with hypoplastic left heart syndrome) and LD1205-03 (diagnosed with schizophrenia)) were sequen! ced for CDR2, EEF2K and UQCRC2; no recessive mutations were identified. * Figure 2: Genomic structure of 16p12.1 region. () A schematic of the 16p12.1 region shows the location of the microdeletion flanked by directly oriented 68-kb segmental duplication blocks (red boxes). The segmental duplication blocks (red and gray boxes) are connected by green and blue lines to indicate direct or inverted orientation, respectively. Also shown are representative genes in the region with the transcriptional direction. CNP indicates the copy-number polymorphism annotated by SNP genotyping16 for this region (CNP2157). () FISH analysis was performed on lymphoblast cell line from GM18956 using fosmid probes mapping to the 68-kb duplicon (WIBR2-2031K01, shown in red) and the flanking unique regions (WIBR2-3632J22 in green and WIBR2-1829F15 in blue). Results show that the 68-kb duplicon is polymorphic (that is, it has a variable number of copies) and that the orientation of the region is inverted in this HapMap sample compared to the human genome reference assembly. High copy numbers of the segmental duplication! s have complicated mapping of the inversion breakpoint for this region. * Figure 3: Representative photographs of individuals with 16p12.1 microdeletion.

Specific consents were obtained to publish these photographs. * Figure 4: Family pedigrees of probands with 16p12.1 microdeletions. () Large CNVs outside the 16p12.1 region in a representative set of individuals with 16p12.1 microdeletions. The CNV regions are indicated by dotted lines, and the cytogenetic extent and size are labeled. We used a 135K NimbleGen array to identify these CNVs (with average probe density of 2.5 kb in regions flanked by segmental duplications and an average probe density of 35 kb in the genomic backbone). CNV calls were made using a Hidden Markov Model CNV-calling algorithm described previously15. () Pedigrees of individuals with 16p12.1 microdeletions and known available parental information. Circles indicate females; squares indicate males. The intellectual disability and congenital malformation category also includes congenital heart defects and seizures. Psychiatric illness includes depression or bipolar disorder, attention deficit hyperactive disorder and abnormal behavior. Note that there is an excess of transmitting parents with the microdeletion who also manifested a ne! uropsychiatric phenotype. NT, not tested.

We identified 60 associations for 8 hematological traits and 29 associations for 12 biochemical traits at genome-wide significance levels (P < 5 × 10−8). Of these, 46 associations were new to this study and 43 replicated previous reports. We compared these associated loci with those reported in similar GWAS in European populations. When the minor allele frequency was >10% in the Japanese population, 32 (94.1%) and 31 (91.2%) of the 34 hematological loci previously reported to be associated in a European population were replicated with P-values less than 0.05 and 0.01, respectively, and 31 (73.8%) and 27 (64.3%) of the 42 European biochemical loci were replicated.

Here we identify the downstream of tyrosine kinase (Dok) family members Dok1, Dok2 and Dok3 as lung tumor suppressors. Single, double or triple compound loss of these genes in mice results in lung cancer, with penetrance and latency dependent on the number of lost Dok alleles. Cancer development is preceded by an aberrant expansion and signaling profile of alveolar type II cells and bronchioalveolar stem cells. In human lung adenocarcinoma, we identify DOK2 as a target of copy-number loss and mRNA downregulation and find that DOK2 suppresses lung cancer cell proliferation in vitro and in vivo. Given the genomic localization of DOK2, we propose it as an 8p21.3 haploinsufficient human lung tumor suppressor.

3,851 affected individuals (cases) and 3,934 unaffected controls drawn from 12 prospective cohort studies and 8 case-control studies. Based on a logistic regression model for genotype trend effect that was adjusted for study, age, sex, self-described ancestry and five principal components, we identified eight SNPs that map to three loci on chromosomes 13q22.1, 1q32.1 and 5p15.33. Two correlated SNPs, rs9543325 (P = 3.27 × 10−11, per-allele odds ratio (OR) 1.26, 95% CI 1.18–1.35) and rs9564966 (P = 5.86 × 10−8, per-allele OR 1.21, 95% CI 1.13–1.30), map to a nongenic region on chromosome 13q22.1. Five SNPs on 1q32.1 map to NR5A2, and the strongest signal was at rs3790844 (P = 2.45 × 10−10, per-allele OR 0.77, 95% CI 0.71–0.84). A single SNP, rs401681 (P = 3.66 × 10−7, per-allele OR 1.19, 95% CI 1.11–1.27), maps to the CLPTM1L-TERT locus on 5p15.33, which is associated with multiple cancer! s. Our study has identified common susceptibility loci for pancreatic cancer that warrant follow-up studies.

However, the molecular basis of the majority of these tumors is unknown2. We identified the transmembrane-encoding gene TMEM127 on chromosome 2q11 as a new pheochromocytoma susceptibility gene. In a cohort of 103 samples, we detected truncating germline TMEM127 mutations in approximately 30% of familial tumors and about 3% of sporadic-appearing pheochromocytomas without a known genetic cause. The wild-type allele was consistently deleted in tumor DNA, suggesting a classic mechanism of tumor suppressor gene inactivation. Pheochromocytomas with mutations in TMEM127 are transcriptionally related to tumors bearing NF1 mutations and, similarly, show hyperphosphorylation of mammalian target of rapamycin (mTOR) effector proteins. Accordingly, in vitro gain-of-function and loss-of-function analyses indicate that TMEM127 is a negative regulator of mTOR. TMEM127 dynamically ! associates with the endomembrane system and colocalizes with perinuclear (activated) mTOR, suggesting a subcompartmental-specific effect. Our studies identify TMEM127 as a tumor suppressor gene and validate the power of hereditary tumors to elucidate cancer pathogenesis.

() Immunoblot of HEK293 cells transfected with wild-type TMEM127 tagged with the Flag epitope at the C terminus (C-Flag-TMEM127) and N terminus (N-Flag-TMEM127), and the N-tagged TMEM127 mutants M158 and M99 or empty murine stem cell virus (MSCV) retroviral vector, probed with an antibody to Flag. A translation product was not detectable from mutant constructs. β-actin was used as a loading control. () Immunoblot of 293E cells transfected with TMEM127 tagged with HA at the N terminus (HA-TMEM127) or the N-Flag-TMEM127 construct shown in , with corresponding empty vector controls, probed with an antibody to HA (left) or Flag (right). β-actin was used as a loading standard. () Confocal microscopy of HEK293T cells expressing wild-type TMEM127 tagged with Flag on the N terminus (left) or C terminus (central) or with an HA N-terminal tag (right). TMEM127 immunoreactivity determined by Flag or HA (red) is present both at the plasma membrane (left) and cytoplasm, with punctate (m! iddle and right) or perinuclear (right, arrows) signals, but is absent from the nucleus (DAPI, blue). These distinct staining patterns were observed with the various constructs in at least three independent experiments (Supplementary Fig. 4b). Plasma membrane–associated TMEM127 distribution was detected on average in 38% (± 13% (s.d.), n = 200) of cells under standard culture conditions. A similar variance in the percentage of plasma membrane–associated signal was noted for each of the constructs. * Figure 2: TMEM127 colocalizes with multiple components of the endomembrane system. (,) Confocal images of HA-TMEM127-transfected HEK293E cells fixed and immunofluorescently labeled with an antibody to the early endosome marker Rab5 (red, ) or to the Golgi marker syntaxin 6 (red, ) along with an antibody to HA (green) and DAPI (blue). Regions identified by the white-dashed rectangles are presented at higher magnification at right and below. Middle, separate presentations of the red and green channel images. Below, overlap (yellow) of red and green pixels, irrespective of their intensity. Right image shows intensity values of the product of the difference of the means (PDMs) as described in the Online Methods. The PDM intensity scale ranges from−0.5 to 0.5 in and −0.6 to 0.6 in . Optical sections are ~0.4 μm thick. Bars, 2 μm. These results are representative of multiple cells assessed in independent experiments. () HEK293E cells stably transfected with HA-TMEM127 were left untreated (top) or were cultured in the presence of a potassium-depleting buffe! r (bottom). Cells were fixed and stained with antibodies specific for HA (green) or Rab5 (red) before imaging. DAPI (blue) shows the nuclei. An increase in plasma-membrane–associated TMEM127 and control Rab5 is seen after inhibition of endocytosis promoted by this treatment. Bars, 10 μm. () HEK293E cells stably transfected with HA-TMEM127 were left untreated (top) or were exposed to ammonium chloride (bottom). Cells were fixed and stained as in (). Expansion of endosomal structures is seen both for HA-TMEM127 and Rab5. Bars, 5 μm. * Figure 3: TMEM127 modulates mTORC1 signaling in vitro and in vivo. () RAS activation measured by a RAS pull-down assay (RAS-GTP expression) of 293E cells with TMEM127 knockdown by two independent shRNA sequences (T1 and T2) or a control knockdown (C) in the absence or presence of serum. Total RAS is shown as the sample loading control.

() Phosphorylation of mTORC1 targets S6K and S6 in 293E cells depleted for TMEM127 by two independent shRNA sequences (T1 and T2); C, GFP control knockdown. () Effects of TMEM127 knockdown (T1) on 4EBP1 and S6 phosphorylation in HEK293 in the presence or absence of 10% serum. C, GFP control knockdown. () Phosphorylation o! f mTORC1 targets, as above, in 293E cells expressing HA-tagged TMEM127 (TMEM127) or a control HA-empty vector (V); T-4EBP1 = total 4EBP1. () Forward scatter fluorescence-activated cell sorting (FACS) analysis of TMEM127 (T1) or control (C) knockdown in HEK293 cells. () Proliferation of TMEM127 or control knockdown 293E cells measured after addition of serum (P < 0.002, t-test). Error bars are ± s.e.m. of triplicate experiments. () S6K phosphorylation in pheochromocytoma lysates. Two normal adrenal medulla samples (NL, lanes 1 and 2) were compared with TMEM127-mutant (Mut TMEM127) samples (lanes 3, 4 and 5, corresponding to samples from families 5, 6 and 1, respectively) and four tumors with wild-type TMEM127 sequence: two sporadic- (lanes 6 and 7), one NF1-mutant- (lane 8) and one VHL-mutant tumor sample (lane 9). Densitometric measurements are shown below each lane (lane 3 was set to 1). β-actin is a loading control. * Figure 4: TMEM127 colocalizes with amino acid–activated mTORC1. () Effect of 1 h amino acid (AA) starvation, followed or not by replenishment (15 min), on S6K and S6 phosphorylation of 293E cells with TMEM127 knockdown by two independent shRNA sequences, T1 and T2. A control knockdown (C) is shown for comparison. () Effect of amino acid (AA) treatment as in on 4EBP1 and S6 phosphorylation of 293E cells overexpressing HA-TMEM127 or empty vector (EV). HA indicates TMEM127 expression. β-actin is the loading control. P-S6K, phosphorylated S6 kinase at residue T389; P-S6, phosphorylated S6 at residues S235-236; P-4EBP1, phosphorylated 4EBP1 at residues T37-46; S6K, total S6 kinase. () HEK293T cells cotransfected with HA-TMEM127 and Myc-mTOR were serum-starved overnight, depleted of amino acids for 1 h followed by re-exposure for 15 min (AA+). Cells were fixed and stained with antibodies specific for HA (green), Myc (red) or DAPI (blue) before imaging. Myc-mTOR was diffusely present in the cytoplasm in the absence of amino acid and became loc! alized to a perinuclear region where TMEM127 was detected after amino acid exposure. Similar results were obtained with two independent TMEM127 constructs. Bars, 5 μm.

Facebook * Twitter * Delicious * Digg Frontotemporal lobar degeneration (FTLD) is the second most common cause of presenile dementia. The predominant neuropathology is FTLD with TAR DNA-binding protein (TDP-43) inclusions (FTLD-TDP)1. FTLD-TDP is frequently familial, resulting from mutations in GRN (which encodes progranulin). We assembled an international collaboration to identify susceptibility loci for FTLD-TDP through a genome-wide association study of 515 individuals with FTLD-TDP. We found that FTLD-TDP associates with multiple SNPs mapping to a single linkage disequilibrium block on 7p21 that contains TMEM106B. Three SNPs retained genome-wide significance following Bonferroni correction (top SNP rs1990622, P = 1.08 × 10−11; odds ratio, minor allele (C) 0.61, 95% CI 0.53–0.71). The association replicated in 89 FTLD-TDP cases (rs1990622; P = 2 × 10−4). TMEM106B variants may confer risk of FTLD-TDP by increasing TMEM106B expression. TMEM106B variants also contribute to genetic risk for FTLD-TDP in in! dividuals with mutations in GRN. Our data implicate variants in TMEM106B as a strong risk factor for FTLD-TDP, suggesting an underlying pathogenic mechanism.

() Manhattan plot of −log10 (observed P value) showing region of genome-wide significant association on chromosome 7. () Regional plot of the TMEM106B-associated interval. Foreground shows scatter plot of the −log10P values plotted against physical position (NCBI build 36). Background shows estimated recombination rates (from phase 2 of the HapMap analysis) plotted to reflect the local LD structure. The color of the dots represents the strength of LD between the top SNP (rs1990622) and its proxies (red, r2 ≥ 0.8; orange, 0.8 < r2 ≥ 0.4; blue, r2 < 0.4). Gene annotations were obtained from assembly 18 of the UCSC genome browser. () Location of the three most strongly associated SNPs (green arrows) relative to the gene structure of TMEM106B (blue bars, 3′ and 5′ untranslated regions; larger red bars, coding exons; thick gray line, intronic regions; gray dashed line, downstream chromosome sequence) and the location of chromosome 7. * Figure 2: TMEM106B expression variation by genotype and disease state. () TMEM106B mRNA expression by QRT-PCR in the frontal cortex differed significantly by genotype at rs1990622 (overall P = 0.027; genotype TT versus TC, P = 0.017; TT versus CC, P = 0.03). Black circles, FTLD-TDP (n = 18); open squares, unaffected (n = 7); horizontal lines, group mean. Significance of P values is denoted by the number of asterisks. () TMEM106B mRNA expression in the frontal cortex was significantly higher in samples from cases with FTLD-TDP compared to those from unaffected controls (P = 0.045). () TMEM106B expression in frontal cortex samples in FTLD-TDP cases with (GRN pos, n = 8) or without (GRN neg, n = 10) GRN mutations compared to unaffected controls (n = 7). Carriers of the GRN mutation had significantly higher levels of TMEM106B expression (overall P = 0.0009; cases with GRN mutations versus controls, P = 0.0005; cases with GRN mutations verses those without, P = 0.002). () When only cases heterozygous at rs1990622 (n = 14) were evaluated, GRN mutatio! ns remained significantly associated with a higher level of TMEM106B expression (P = 0.039) in the frontal cortex. QRT-PCR was performed in triplicate for all expression studies. Expression values were normalized to the geometric mean of two housekeeping genes and are shown here relative to a single reference control sample23. Error bars, s.e.m. Normalized gene expression data and sample genotype and gender data used for these analyses are provided in Supplementary Data 1 and 2. * Figure 3: Manhattan plot in cases with and without GRN mutations. (,) Manhattan plot of −log10 (observed P value) across the genome in cases with () and without () GRN mutations. The subset of cases with GRN mutations shows regions of genome-wide significant association on chromosomes 7 and 17. The chromosome 17 association was confirmed to be driven by a shared haplotype in carriers of the C1477T (R493X) mutation in GRN, representing ~20% of mutation-positive cases; however, the chromosome 7 association is not related to any single GRN mutation and remains when the cases with the C1477T mutation are removed from the analysis (P = 1.4 × 10−10). The same locus on chromosome 7 identified in the cases with the GRN mutation is also the strongest signal in the cases without the GRN mutation, although it does not reach genome-wide significance. A list of the SNPs with the highest signals in is given in Supplementary Table 8.

Previous studies have identified several genetic loci associated with typical AF. We sought to identify common genetic variants underlying lone AF. This condition affects a subset of individuals without overt heart disease and with an increased heritability of AF. We report a meta-analysis of genome-wide association studies conducted using 1,335 individuals with lone AF (cases) and 12,844 unaffected individuals (referents). Cases were obtained from the German AF Network, Heart and Vascular Health Study, the Atherosclerosis Risk in Communities Study, the Cleveland Clinic and Massachusetts General Hospital. We identified an association on chromosome 1q21 to lone AF (rs13376333, adjusted odds ratio = 1.56; P = 6.3 × 10−12), and we replicated this association in two independent cohorts with lone AF (overall combined odds ratio = 1.52, 95% CI 1.40–1.64; P = 1.83 × 10−21). rs13376333 is intronic to KCNN3, wh! ich encodes a potassium channel protein involved in atrial repolarization.

We describe a previously unknown autosomal recessive disease characterized by microcephaly, early-onset, intractable seizures and developmental delay (denoted MCSZ). Using genome-wide linkage analysis in consanguineous families, we mapped the disease locus to chromosome 19q13.33 and identified multiple mutations in PNKP (polynucleotide kinase 3′-phosphatase) that result in severe neurological disease; in contrast, a splicing mutation is associated with more moderate symptoms. Unexpectedly, although the cells of individuals carrying this mutation are sensitive to radiation and other DNA-damaging agents, no such individual has yet developed cancer or immunodeficiency. Unlike other DNA repair defects that affect humans, PNKP mutations universally cause severe seizures. The neurologi! cal abnormalities in individuals with MCSZ may reflect a role for PNKP in several DNA repair pathways. View full text Figures at a glance * Figure 1: Pedigrees of MCSZ families. Family 1 represents a consanguineous Palestinian pedigree in Jordan. Family 2 shows another consanguineous Palestinian pedigree that is reportedly unrelated to family 1, also in Jordan. Family 3 is also consanguineous and Palestinian, but the family now resides in the United States. Family 4 is from the Kingdom of Saudi Arabia, and the parents were not known to be consanguineous. Family 5 is from Turkey, and the parents were not known to be related. Family 6 is of mixed European descent from the United States (German-Irish). Family 7 is also of mixed European (Swedish, Italian, Irish and English) heritage, from the United States. The individuals from whom samples were obtained are indicated by the label 'DNA'. The individuals from whom we established lymphoid cell lines are indicated by the label 'Cells'. Cells and DNA were available for all members of family 7. * Figure 2: Brain MRIs of individuals with MCSZ. Representative MRI images are shown from families 4 (; severely affected) and 7 (; moderately affected) with aged-matched controls. MRIs of severely affected individuals from other families were similar to the representative images in . Sagittal images are shown on the left (T1), axial images in the middle (T2) and coronal images on the right (T2 () and FLAIR ()), with the MRI sequence noted above the image. The MRIs show that, despite the microencephaly (small brain), the gyral pattern is not clearly abnormal, indicating an absence of visible neuronal migration abnormality. The cerebellum is proportionately small compared to the cerebrum, and the subpallium (basal ganglia or ventral cerebrum) is proportionate to the pallium (dorsal cerebrum). There is no evidence of atrophy or glial scarring. Scale bar indicates 5 cm for both unaffected and MCSZ images. * Figure 3: PNKP mutations in individuals with MCSZ. () The diagram shows four different mutations identified in human PNKP genomic DNA, mRNA and protein, including protein domains (forkhead is indicated by 'FHA'). The human PNKP gene consists of 17 exons (boxes) and encodes a peptide of 521 amino acids. Filled boxes represent untranslated regions and open boxes represent coding regions. Lines connecting the exons represent introns. () Protein blot for PNKP. Lanes 1 and 2 show samples from an individual with MCSZ (VI:3 with the E326K mutation) and an unaffected brother (VI:1), respectively, from family 3. Lanes 3 and 4 represent individuals with MCSZ (II:1 and II:4, with both a 17-bp duplication (dup) and a 17-bp intron 15 deletion (del)) from family 7. In contrast, lanes 5 and 6 represent the father (I:1) and brother (II:3) from this family, who are both heterozygous for the 17-bp intron 15 del. The band indicates a molecular weight of ~60 kDa (predicted size 57 kDa). Anti–β-actin is a loading control. () RT-PCR products o! f mRNA from members of family 7 show the expected size from the normal copy of PNKP cDNA (636 bp), seen in lanes 3 and 4 from unaffected carriers. The 17-bp dup results in a 653-bp fragment, seen in lanes 1, 2 and 3. The band in lanes 1, 2 and 4 corresponding to a size of 548 bp is found in samples with the intron 15 deletion lacking exon 15 (determined from sequencing; data not shown). A small amount of normal-sized transcript is seen in lanes 1 and 2 with higher exposure (data not shown), indicating that a small amount of normal PNKP mRNA can be produced. * Figure 4: Lymphocytes from individuals with MCSZ show abnormal DNA repair. () Examples of comet assay results. The intensity of the fluorescence is represented in pseudocolor, as the electrical field drives damaged, loose DNA from left to right. The image at left shows a cell with 50% tail DNA with the body of the nucleus (green) on the left and the tail of the comet derived from the damaged DNA extending to the right. The images middle and right show progressively less damage, with 29% and 11% tail DNA, respectively. () After hydrogen peroxide treatment with 0 min for recovery, cells show their maximum damage. Cells derived from individuals with MCSZ (blue and red) show significant impairment in their ability to repair DNA after hydrogen peroxide was removed, whereas cells derived from unaffected family members were able to repair DNA much more efficiently. () After camptothecin (CPT) treatment, there was also statistically significantly slower repair in cells derived from individuals with MCSZ compared with those from unaffected family members (g! reen and purple). However, after 45 min, the MCSZ-derived cells were able to repair all CPT damage, in contrast to hydrogen peroxide–treated cells. All cells were derived from family 7. Blue diamonds and red squares indicate cells from individuals with MCSZ carrying the exon 14 17-bp duplication and the intron 15 17-bp deletion (II:1 and II:4, respectively); green triangles represent an unaffected parent who is heterozygous for the intron 15 17-bp deletion (I:1); purple crosses represent an unaffected sibling with no mutation (II:2). *P = 0.05; **P < 0.005; ***P < 0.0005.

Within a dog breed, linkage disequilibrium is extensive1, 2, enabling genome-wide association (GWA) with only around 15,000 SNPs and fewer individuals than in human studies1, 3. Incidences of specific diseases are elevated in different breeds, indicating that a few genetic risk factors might have accumulated through drift or selective breeding. In this study, a GWA study with 81 affected dogs (cases) and 57 controls from the Nova Scotia duck tolling retriever breed identified five loci associated with a canine systemic lupus erythematosus (SLE)–related disease complex that includes both antinuclear antibody (ANA)–positive immune-mediated rheumatic disease (IMRD) and steroid-responsive meningitis-arteritis (SRMA). Fine mapping with twice as many dogs validated these loci. Our results indicate that the homogeneity of strong genetic risk factors within dog breeds allows multigenic! disorders to be mapped with fewer than 100 cases and 100 controls, making dogs an excellent model in which to identify pathways involved in human complex diseases. View full text Figures at a glance * Figure 1: Genome-wide association identified five loci associated with a canine SLE-related disease. () Genome-wide association of all cases together showed one strong peak on chromosome 32. () For ANA-positive IMRD dogs, four highly associated regions were found (canine chromosomes 3, 8, 11 and 24), with chromosomes 8 and 24 reaching genome-wide significance. () SRMA dogs showed one region of genome-wide significance on chromosome 32. * Figure 2: Fine mapping and validation of three risk loci for ANA-positive IMRD. (–) The strongest associations were found on chromosomes Cfa 11 (), Cfa 24 () and Cfa 3 (). Plots show haplotype (dark blue dots, with lines connecting SNPs on the same haplotype) and single SNP (black dots) associations in NSDTRs. * Figure 3: The Cfa32 locus confers risk to multiple subphenotypes. (–) A 1.6-Mb region was defined where ANA-positive IMRD dogs (), SRMA-affected dogs () and all cases together () show association. This region might reflect a common locus involved in all phenotypes or could contain multiple separate risk factors. The region is potentially composed of three separate associated peaks, where the leftmost peak is most strongly associated in all three analyses. Plots show haplotype (dark blue dots, with lines connecting SNPs on the same haplotype) and single SNP (black dots) associations in NSDTRs. * Figure 4: The products of four of the candidate genes are involved in T-cell activation through the NF-AT pathway. PPP3CA is activated by the influx of calcium, which in turn results in the activation of the transcription factor NF-AT. PPP3CA is also reported to be the target of the immunosuppressive drugs cyclosporine A and FK506. HOMER2 competes with PPP3CA for binding to NF-AT, which acts as a negative regulator of T-cell activation. Both DAPP1 and PTPN3 inhibit T-cell activation through the TCR and reduce activation of reporter genes driven by NF-AT.

To identify regulatory DNA active in human pancreatic islets, we profiled chromatin by formaldehyde-assisted isolation of regulatory elements2, 3, 4 coupled with high-throughput sequencing (FAIRE-seq). We identified ~80,000 open chromatin sites. Comparison of FAIRE-seq data from islets to that from five non-islet cell lines revealed ~3,300 physically linked clusters of islet-selective open chromatin sites, which typically encompassed single genes that have islet-specific expression. We mapped sequence variants to open chromatin sites and found that rs7903146, a TCF7L2 intronic variant strongly associated with type 2 diabetes5, is located in islet-selective open chromatin. We found that human islet samples heterozygous for rs7903146 showed allelic imbalance in islet FAIRE signals and that the variant alters enhancer activity, indicating that genetic variation at this locus acts in cis with local chromati! n and regulatory changes. These findings illuminate the tissue-specific organization of cis-regulatory elements and show that FAIRE-seq can guide the identification of regulatory variants underlying disease susceptibility.

DNA fragments recovered in the aqueous phase are then sequenced. () Reads obtained from sequencing were highly concordant with FAIRE signals obtained from tiling microarrays covering the ENCODE pilot project regions (FAIRE-chip). Arrows indicate the direction of gene transcription. * Figure 2: Both proximal and distal FAIRE sites harbor functional regulatory elements. () Genes with high expression in islets (top 20%, red) have more FAIRE enrichment at promoters than genes with moderate (middle 20%, green) or low (bottom 20%, blue) expression. () Promoters (−750 to +250 bp) bound by RNA polymerase II, HNF4A or HNF1A in human islets11 are significantly over-represented among islet FAIRE sites (red dash indicates expected value; all bars, P < 0.001). () Intergenic islet-selective and ubiquitous FAIRE sites that are located >2 kb from a TSS are enriched for evolutionarily conserved sequences (P < 0.001), predicted regulatory modules (PreMod, P < 0.001) and transcription factor binding sites (conserved TFBS and MotifMap, both P < 0.001). CTCF binding, however, is enriched in ubiquitous FAIRE sites only. Over half of intergenic open chromatin sites are coincident with an experimentally or computationally determined functional annotation (expected value for random sites, 27%). () Open chromatin is most enriched directly at sites of experimenta! lly determined CTCF binding. () In contrast to ubiquitous FAIRE sites, islet-selective FAIRE sites are rarely located within 2 kb upstream of a TSS or in the first exon of a gene but are instead located predominantly in more distal regions. Shown is the percentage of bases covered by each annotation category in islet-selective FAIRE sites (blue), ubiquitous FAIRE sites (red) and the mappable genome (gray). * Figure 3: Islet-selective FAIRE sites form clusters of open regulatory elements (COREs). () FAIRE sites are highly clustered. We divided the genome in windows of varying size (x axis) and calculated a χ2 statistic to determine if the number of windows with 0, 1 or >1 FAIRE sites differed from randomly distributed sites. The highest significance was observed in ~20 kb windows. () Same procedure as in but for islet-selective sites. () We defined islet-selective clusters of open chromatin regulatory elements (COREs) as three or more islet-selective FAIRE sites separated from each other by <20 kb. () We identified 3,348 islet-selective COREs (blue points). Fewer COREs were generated using randomized FAIRE sites (orange points) and they were smaller than in vivo COREs. () Most islet-selective COREs were associated with a single gene. () RefSeq genes associated with islet-selective COREs were on average inactive in non-islet human tissues, except for brain tissue. Asterisks indicate P < 1 × 10−5 (one-way ANOVA). a.u., arbitrary units. () Chromatin landscape of the!

Bottom, a closer view of a portion of the PDX1 islet-selective CORE, with islet-selective open chromatin sites at previously characterized regulatory elements (area I–III and area IV) and in an evolutionarily conserved putative enhancer. * Figure 4: Allele-specific open chromatin and enhancer activity at the TCF7L2 locus. () Schematic representation of how FAIRE-seq enables the identification of human sequence variants located in islet open chromatin. From ~4 million SNPs present in dbSNP with average heterozygosity >1%, 38 SNPs associated with T2D or fasting glycemia mapped to islet open chromatin sites. The analysis was carried out with all SNPs in strong linkage disequilibrium (r2 > 0.8) with a fasting glycemia- or T2D-associated variant, which are labeled as FG or T2D SNPs, and FAIRE-seq sites identified with a liberal threshold. () Among TCF7L2 variants in linkage disequilibrium with rs7903146 (r2 > 0.2, top), only rs7903146 maps to an islet-selective FAIRE site. () In all nine human islet samples that were heterozygous for rs7903146, the risk allele T was more abundant than the non-risk C allele in the open chromatin fraction, in contrast to input DNA or genomic DNA from unrelated heterozygous individuals. () Allelic imbalance for the open chromatin at rs7903146 was verified in independ! ent assays using quantitative Sanger sequencing (see also Supplementary Fig. 4b). (,) The risk allele T of rs7903146 shows greater enhancer activity than the non-risk allele C in MIN6 cells () and 832/13 cells (). The s.d. values represent four independent clones for each alleles.

Serpentine soils, characterized by high heavy-metal content and low calcium-to-magnesium ratios, are a classic context for studying adaptation of plants to local soil conditions6, 7. To investigate whether Arabidopsis lyrata is locally adapted to serpentine soil, and to map the polymorphisms responsible for such adaptation, we pooled DNA from individuals from serpentine and nonserpentine soils and sequenced each 'gene pool' with the Illumina Genome Analyzer. The polymorphisms that are most strongly associated with soil type are enriched at heavy-metal detoxification and calcium and magnesium transport loci, providing numerous candidate mutations for serpentine adaptation. Sequencing of three candidate loci in the European subspecies of A. lyrata indicates parallel differentiation of ! the same polymorphism at one locus, confirming ecological adaptation, and different polymorphisms at two other loci, which may indicate convergent evolution.

However, the mechanisms regulating postmitotic cell growth in plants remain unknown. Here we report the discovery of a basic helix-loop-helix (bHLH) transcription factor called RSL4 (ROOT HAIR DEFECTIVE 6-LIKE 4) that is sufficient to promote postmitotic cell growth in Arabidopsis thaliana root-hair cells. Loss of RSL4 function resulted in the development of very short root hairs. In contrast, constitutive RSL4 expression programmed constitutive growth, resulting in the formation of very long root hairs. Hair-cell growth signals, such as auxin and low phosphate availability, modulate hair cell extension by regulating RSL4 transcript and protein levels. RSL4 is thus a regulator of growth that integrates endogenous developmental and exogenous environmental signals that together control postmitotic growth in root hairs. The control of postmitotic growth by transcription factors may represent a general mecha! nism for regulating cell size across diverse organisms.

Genome-wide association studies (GWAS) of parasite traits have been hampered by the lack of high-throughput genotyping methods, inadequate knowledge of parasite population history and time-consuming adaptations of parasites to in vitro culture. Here we report the first Plasmodium GWAS, which included 189 culture-adapted P. falciparum parasites genotyped using a custom-built Affymetrix molecular inversion probe 3K malaria panel array with a coverage of ~1 SNP per 7 kb. Population structure, variation in recombination rate and loci under recent positive selection were detected.

Although high-throughput epistasis data from model organisms are being generated and used to construct genetic networks1, 2, 3, the extent to which genetic epistasis reflects biologically meaningful interactions remains unclear4, 5, 6. We have addressed this question through in silico mapping of positive and negative epistatic interactions amongst biochemical reactions within the metabolic networks of Escherichia coli and Saccharomyces cerevisiae using flux balance analysis. We found that negative epistasis occurs mainly between nonessential reactions with overlapping functions, whereas positive epistasis usually involves essential reactions, is highly abundant and, unexpectedly, often occurs between reactions without overlapping functions. We offer mechanistic explanations of these findings and experimentally validate them for 61 S. cerevisiae gene pairs.

Blue and red indicate positive and negative epistasis, respectively, whereas the areas of the circles and squares are proportional to the absolute values of ϵ and , respectively, with the scales given on the top and left sides of each panel. Solid symbols indicate statistically significant epistasis (P < 0.05), whereas open symbols indicate insignificant epistasis. The shaded area in the lower right corner shows relationships between nonessential genes. Fitness values of strains with genes replaced or inserted by LEU2, relative to the wild types, are presented on the x axis. () Epistasis among eight haploinsufficient genes, measured in diploid cells after deletion of one allele per gene. All genes belong to different functional categories with the exception of RPS5 and RPL14A, both of which encode ribosomal proteins. () Epistasis among nine haplosufficient genes, measured in haploid cells after reduction of protein expression of essential genes! and deletion of nonessential genes. All genes belong to different functional categories, with the exception of GAA1 and GAS1. MET22 and CHO2 are metabolic genes, with FBA-predicted scaled epistasis equal to 1. '−' indicates that double-perturbation cells could not be obtained, probably because of unsuccessful experiments or synthetic lethality. '?' indicates that epistasis could not be measured owing to the lack of fitness effect of single perturbations with the URA3 marker. In Supplementary Figure 3, we explain why here negative epistasis between nonessential genes seems to be more abundant than expected.
