Diabetologia. 2020;63(12):2605–2615. doi: 10.1007/s00125-020-05276-4.Diabetes diagnosed at <6 months of age is often of monogenic origin. However, 10-15% of affected infants do not have a pathogenic variant in one of the 26 known neonatal diabetes genes. In this study, 166 infants diagnosed at <6 months of age without such pathogenic variants showed all the the classic feat...

PMID: 33619380.In brief: In this genome-wide association study, the authors were able to disentangle the mechanism that uncouples adiposity from its known cardiometabolic complications. They identified 62 genomic loci, at which the same allele is associated with both higher adiposity and lower cardiometabol...
