Haifan Lin and colleagues report the identification in Drosophila of a protein complex composed of Hsp90 Piwi, and the Hsp70/Hsp90 Organizing Protein Homolog (Hop) and demonstrate the function of this complex in buffering against morphological changes in a sensitized background.
Ewan Pearson and colleagues report a genome-wide association study for glycemic response to metformin in individuals with type 2 diabetes. They identify variants near ATM associated with treatment success.
Emmanuel Mignot and colleagues report genome-wide association analyses identifying a new susceptibility locus for narcolepsy. They identify associated variants in the 3′ untranslated region of P2RY11, a purinergic receptor that modulates immune cell viability.
Zi-Jiang Chen and Yongyong Shi report a genome-wide association study for polycystic ovary syndrome, a common metabolic and endocrine disorder in women. They identified three susceptibility loci associated with this condition.
Krina Zondervan and colleagues report a genome-wide association study for endometriosis. The authors identify a susceptibility locus on chromosome 7p15.
Michel Georges and colleagues perform high-throughput resequencing of 63 positional candidate genes identified through genome-wide association studies to search for rare coding variants influencing risk of Crohn's disease. They identify low-frequency coding variants in IL23R that confer protection against inflammatory bowel disease but conclude that rare coding variants in these positional candidates do not make a large contribution to Crohn's disease risk.
Michel Georges and colleagues identify a founder mutation in CCDC39 associated with primary ciliary dyskinesia in Old English Sheepdogs. They further show that mutations in human CCDC39 cause a similar phenotype and that CCDC39 is required for the assembly of inner dynein arms and the dynein regulatory complex.
Paul Brennan, Stephen Chanock and colleagues performed a genome-wide association study for renal carcinoma. They identified two genetic susceptibility loci.
Rebecca Burdine and colleagues show that CCDC40 is required for motile cilia function and correct left-right patterning in mouse, zebrafish and humans. Their findings highlight an essential role for CCDC40 in the assembly of inner dynein arms and dynein regulatory complexes.
Loes van der Zanden and colleagues report results of a genome-wide association study of hypospadias, a common congenital malformation of the male external genitalia. They show that variants in DGKK on the X chromosome are associated with substantially elevated risk of this disorder.
Miles Parkes and colleagues report results of a large genome-wide association meta-analysis and replication study for Crohn's disease. They identify 30 new susceptibility loci for this inflammatory bowel disease and implicate several interesting candidate genes in disease pathogenesis.
Joris Veltman, Han Brunner and colleagues report results of a family based exome sequencing study of ten individuals with unexplained mental retardation. They identified and validated de novo mutations in nine genes, six of which are likely to be pathogenic based on functional criteria, suggesting an important role for de novo point mutations in the etiology of unexplained mental retardation.
Holger Prokisch and colleagues report whole-exome sequencing of an individual with severe complex I deficiency, followed by screening in an additional 120 cases. They identify mutations in ACAD9 as causal for complex I deficiency.
George Daley and John Rinn and colleagues identify large intergenic non-coding RNAs that are upregulated during reprogramming of induced pluripotent stem cells, and they show a functional role for large intergenic non-coding RNA-RoR in induced pluripotent stem cell derivation.
Matthieu Reymond and colleagues show that natural genetic variants at the SRF3 locus underlie genetic incompatibilities between European and central Asian accessions of Arabidopsis.
Richard Houlston and colleagues report results of a genome-wide association study of Hodgkin's lymphoma. They identify three new susceptibility loci at 2p16 (REL), 8q24 and 10p14 (GATA3) and confirm a strong role for the HLA region in disease etiology.
Mark Achtman and colleagues report the whole-genome sequencing of 11 Yersinia pestis isolates, the causative agent of the plague. Their phylogeographic analysis on a larger dataset of Y. pestis global isolates suggests historical routes of transmission.
Jun Wang and colleagues report the resequencing of six elite maize inbred lines. The authors identified over 1 million SNPs and 30,000 insertion or deletion polymorphisms in this agricultural crop.
Montserrat Garcia-Closas and colleagues report a genome-wide association study for bladder cancer. They identify three new susceptibility loci on chromosomes 22q13.1, 19q12 and 2q37.1.
Ian Tomlinson, Richard Houlston, Malcolm Dunlop and colleagues report results of a large genome-wide association study of colorectal cancer. They identify four new risk loci and suggest that many more loci of similar effect size are likely to exist.
