This GWAS meta-analysis combined data from five well known ethnically diverse cohorts (Framingham Heart Study, Atherosclerosis Risk in Communities Study, Multiethnic Study of Atherosclerosis, Taiwan-Metabochip Study for Cardiovascular Disease, and Singapore Prospective Study) to evaluate glycemic and erythrocytic genetic variants impacting HbA1c in individuals of European, African American, and East Asians ancestry. The study found new and known glycemic and...

To read the full abstract: Cell 2019;177 (3):59–-607.e9. PMID 31002796.A recent GWAS showed that the heritability of thinness was comparable to that of obesity (1). Some loci showed effects across the entire BMI distribution. This is also true for variants in MC4R. The present study analyzed data on ˜0.5 million people from UK Biobank, with a focus on 61 nonsynonymous var...

To read the full abstract: PLoS Genet. 2019; 15(1):e1007603.This genome wide association study reveals new insights into the genetic basis of thinness by investigating a large cohort of healthy persistently thin individuals. In the past, it has been speculated that inheritance of thinness may constitute a protective factor against environmental factors disposing to obesity (1). Neverthel...
