Xue-Jun Zhang, Jun Wang and colleagues identify mutations in MVK in disseminated superficial actinic porokeratosis, a disorder characterized by defects in epidermal keratinization. MVK encodes mevalonate kinase, an enzyme involved in the biosynthesis of cholesterol and isoprenoids.
Peter Donnelly and colleagues report a genome-wide association study for Barrett's esophagus, a common premalignant condition associated with stomach acid reflux and predisposing to esophageal adenocarcinoma. They identify two loci associated with susceptibility to Barrett's esophagus.
Carl Anderson and colleagues report dense genotyping, using the Immunochip array, of 2,861 primary biliary cirrhosis (PBC) cases and 8,514 controls. They identify three loci newly associated with PBC, and their fine-mapping of previous susceptibility loci identifies five regions with multiple independent common, low-frequency and rare variant associations.
Elizabeth Holliday and colleagues report a genome-wide association study for ischemic stroke. They identify common variants at 6p21.1 associated with large artery atherosclerosis (LAA), a major subtype of ischemic stroke.
Roman Thomas and colleagues report exome sequencing of 29 small-cell lung cancers (SCLCs), 2 SCLC genomes and transcriptomes of 15 SCLCs. They identify recurrent mutations in the CREBBP, EP300 and MLL genes encoding histone modifiers. They identify mutations in SLIT2 and EPHA7, which have a role in axon guidance and cell migration, and focal amplifications of FGFR1.
Sekar Seshagiri and colleagues report exome, transcriptome and copy-number alteration data in small-cell lung cancer. The authors find SOX2 amplification in 27% of samples and also identify a recurrent RFL-MYCL1 fusion.
John Maris and colleagues identify common variants at 6q16 associated with neuroblastoma susceptibility. The risk variants are located near the HACE1 and LIN28B genes, both of which show altered expression in advanced neuroblastomas.
Robert Jenkins and colleagues report fine mapping of the glioma risk region at 8q24.21. They identify a new low-frequency variant in the region that is strongly associated with risk of oligodendroglial tumors and astrocytomas with IDH1 or IDH2 mutation.
Brian Fowler, David Rosenblatt and colleagues show that mutations in the ABC transporter gene ABCD4 cause a new inborn error of vitamin B12 metabolism. ABCD4 colocalizes with the lysosomal proteins LAMP1 and LMBD1 and may be involved in intracellular processing of vitamin B12.
Ningli Wang, Tin Aung and colleagues report genome-wide association analyses for primary angle closure glaucoma, a major cause of blindness worldwide. They identify three loci newly associated with this disease.
Ze-Guang Han and colleagues report exome sequencing of ten hepatitis B virus–positive hepatocellular carcinomas. They identify recurrent somatic mutations in ARID1A and mutation signatures that may reflect mutagenic exposures.
David Reich and colleagues report direct characterization of the human mutation rate based on analysis of 85,289 Icelandic individuals genotyped at 2,477 autosomal microsatellite loci. They use this mutation rate to build a model of microsatellite evolution and estimate key evolutionary parameters.
Joel Hirschhorn and colleagues examine height-associated SNPs in northern- and southern-European populations. They report evidence of widespread weak selection on standing variation for height in humans.
Richard O'Connell and colleagues report the genomes and transcriptomes of two Colletotrichum plant fungal pathogens. C. higginsianum infects Arabidopsis thaliana, and C. graminicola infects maize (Zea mays); comparative genomics in both species lead to molecular insights into the transition from biotrophic to necrotrophic life stages.
Zi-Jiang Chen and colleagues report a genome-wide association analysis for polycystic ovary syndrome (PCOS) in Han Chinese. They identify eight new susceptibility loci for PCOS in this population.
Ching-Lung Cheung and colleagues report a genome-wide association study for thyrotoxic periodic paralysis (TPP), a life-threatening complication of thyrotoxicosis, in a Chinese population. They identify associated variants at 17q24.3 near KCNJ2.
Nicholas Thomson and colleagues report whole-genome sequencing of 132 globally distributed isolates of Shigella sonnei, a cause of human dysentery. Their phylogeographic analyses suggest that the current S. sonnei population is under 500 years old, and the authors are able to trace several distinct lineages that have spread out of Europe to other continents over the last few decades.
Jane Carlton and colleagues report the genome sequencing, de novo assembly and annotation of four Plasmodium vivax reference strains from diverse geographic locations. Their cross-species comparisons show that P. vivax has greater genetic diversity than Plasmodium falciparum.
Jane Carlton, Kazuyuki Tanabe and colleagues report the draft genome sequences of three Plasmodium cynomolgi strains isolated from infected monkeys. Their comparative genomic analysis with P. vivax and P. knowlesi offers insights into these simian malaria parasites.
David Goldstein, Mohamad Mikati and colleagues report identification of de novo mutations in ATP1A3 in alternating hemiplegia of childhood, which is a rare neurodevelopmental syndrome characterized by recurrent hemiplegic episodes and distinct neurologic manifestations.
