Genetic studies of body mass index yield new insights for obesity biology
A genome-wide association study and Metabochip meta-analysis of body mass index (BMI), a measure commonly used to define obesity and assess adiposity, in up to 339,224 individuals provide strong support for a role of the central nervous system in obesity susceptibility.
Host-microbe interactions have shaped the genetic architecture of inflammatory bowel disease
A meta-analysis of Crohn’s disease and ulcerative colitis genome-wide association scans is undertaken, followed by extensive validation of significant findings, with a combined total of more than 75,000 cases and controls.
Biological Insights From 108 Schizophrenia-Associated Genetic Loci
Associations at DRD2 and several genes involved in glutamatergic neurotransmission highlight molecules of known and potential therapeutic relevance to schizophrenia, and are consistent with leading pathophysiological hypotheses.
GenABEL: an R library for genome-wide association analysis
UNLABELLED Here we describe an R library for genome-wide association (GWA) analysis. It implements effective storage and handling of GWA data, fast procedures for genetic data quality control,…
LD Score regression distinguishes confounding from polygenicity in genome-wide association studies
It is found that polygenicity accounts for the majority of the inflation in test statistics in many GWAS of large sample size, and the LD Score regression intercept can be used to estimate a more powerful and accurate correction factor than genomic control.
Partitioning heritability by functional annotation using genome-wide association summary statistics
A new method is introduced, stratified LD score regression, for partitioning heritability from GWAS summary statistics while accounting for linked markers, which is computationally tractable at very large sample sizes and leverages genome-wide information.
Genome-wide Association Analysis Identifies 14 New Risk Loci for Schizophrenia
It is estimated that 8,300 independent, mostly common SNPs contribute to risk for schizophrenia and that these collectively account for at least 32% of the variance in liability.
Genome-wide association analyses identify 44 risk variants and refine the genetic architecture of major depression
A genome-wide association meta-analysis of individuals with clinically assessed or self-reported depression identifies 44 independent and significant loci and finds important relationships of genetic risk for major depression with educational attainment, body mass, and schizophrenia.
Defining the role of common variation in the genomic and biological architecture of adult human height
The results indicate a genetic architecture for human height that is characterized by a very large but finite number of causal variants, including mTOR, osteoglycin and binding of hyaluronic acid.
