Coordinated hormonal interactions in response to feeding and fasting regulate glucose homeostasis.

A meta-analysis of genome-wide association studies of type 2 diabetes (T2D) identifies more than 600 T2D-associated loci; integrating physiological trait and single-cell chromatin accessibility data at these loci sheds light on heterogeneity within the T2D phenotype.

Analysis of the imprinted KLF14 locus shows that the type 2 diabetes risk alleles in this region act in adipocytes to reduce KLF14 expression and modulate the expression of almost 400 genes in trans, leading to a shift in body-fat distribution and insulin resistance specifically in females.

A multi-ancestry genome-wide association study for age at menarche followed by fine mapping and downstream analysis implicates 665 pubertal timing genes, such as the G-protein-coupled receptor 83 (GPR83) and other genes expressed in the ovaries involved in the DNA damage response.

Previous genome-wide association studies have identified risk loci for pancreatic cancer but were centered on individuals of European ancestry. Here the authors identify GP2 gene variants associated with pancreatic cancer susceptibility in populations of East Asian ancestry.

Genome-wide association analyses in the Japanese population and trans-ancestry meta-analyses identify new risk loci for coronary artery disease. A polygenic risk score derived from these findings identifies individuals with increased risk of long-term cardiovascular mortality.

A trans-ancestry meta-analysis of GWAS of glycemic traits in up to 281,416 individuals identifies 99 novel loci, of which one quarter was found due to the multi-ancestry approach, which also improves fine-mapping of credible variant sets.

Thousands of genetic loci are known to associate with human height, but these are mainly based on studies in European ancestry populations. Here, Akiyama et al. construct a genotype reference panel for the Japanese population followed by GWAS and report 573 height associated variants in 191,787 Japanese.

The prediction of mortality due to prostate cancer remains challenging. Here, the authors perform trans-ancestry metaanalysis with a focus on binding sites of the androgen receptor and develop a polygenic risk score.

Hundreds of genetic loci associated with age at menopause, combined with experimental evidence in mice, highlight mechanisms of reproductive ageing across the lifespan.

Genetic and environmental factors impact on lung function, important in the diagnosis of pulmonary diseases. Here the authors use imputation of genotypes to the 1000 Genomes Project reference panel to identify novel, low frequency variants associated with lung function.

Multi-ancestry genome-wide association analyses for birth weight in 153,781 individuals identified 60 genomic loci in which birth weight and fetal genotype were associated and found an inverse genetic correlation between birth weight and cardiometabolic risk.

Sex differences in fasting glucose and insulin have been identified, but the genetic loci underlying these differences have not. Here, the authors perform a meta-analysis of genome-wide association studies to detect sex-specific and sex-dimorphic loci associated with fasting glucose and insulin.

Genome-wide association studies (GWAS) have become a key tool to discover genetic markers for complex traits; however, environmental factors that interact with genes are rarely considered. Here, the authors conduct a GWAS of obesity traits, and find that smoking may alter genetic susceptibilities.

Andrew Morris, Mark McCarthy, Michael Boehnke and colleagues report a meta-analysis of genome-wide association studies for type 2 diabetes, including 26,488 cases and 83,964 controls from populations of European, east Asian, south Asian and Mexican and Mexican American ancestry. They identify seven loci newly associated with type 2 diabetes and examine the genetic architecture of disease across populations.

Rachel Freathy and colleagues report results of a large-scale genome-wide association study of birth weight. They identify four loci newly associated with this trait and find overlap between birth weight–associated loci and those influencing adult height and metabolism.

Genome-wide analysis in 212,453 Japanese individuals identifies loci associated with 42 diseases. Comparative analysis with European populations identifies East Asian–specific associations.

Samuli Ripatti and colleagues report the results of a genome-wide association study for circulating lipid levels based on 1000 Genomes Project imputation. Their results implicate several new loci, refine the association signals at many established loci and highlight the impact of low-frequency variants on lipid traits.

Sequencing data from two large-scale studies show that most of the genetic variation influencing the risk of type 2 diabetes involves common alleles and is found in regions previously identified by genome-wide association studies, clarifying the genetic architecture of this disease.

Jose Florez, Claudia Langenberg, Erik Ingelsson, Inga Prokopenko, Inês Barroso and colleagues perform large-scale association analyses using the Metabochip to gain further insights into the genetic architecture of glucose regulation.
