In Brief: This comprehensive genome-wide association study (GWAS) identified over 20 000 loci associated with adult height. This groundbreaking research revealed that up to 21% of the human genome can be linked to variation in human height, providing a deeper understanding of the complex regulation of human height.Commentary: This one of the largest GWAS to date involving 5.4 million individuals. It discovered 12 111 independent SNPs associated with adul...

Brief summary: This international multicentre study collected data from 104 290 children and adolescents (6 months-18 years-old), to compare prevalence of diabetic ketoacidosis (DKA) at diagnosis of type 1 diabetes (T1D) before and during the COVID-19 pandemic. Prevalence of DKA at T1D diagnosis increased from 27.3% pre-pandemic to 39.4% during the pandemic, and the increased trends were associated with the pandemic containment measures.DKA is a life-thr...

Brief summary: In this experimental study, genome editing and in vitro pancreatic differentiation of human pluripotent stem cells (SC) were used to generate ZNT8 loss-of-function (LOF) SC-β-cells. These cells showed accelerated functional maturation, increased insulin secretion and improved resistance to metabolic stress. Transplantation of ZnT8 LOF SC-β-cells into mice with preexisting diabetes significantly improved their glucose levels.<...
