Nat Commun. 2021 Jan 11;12(1):256. doi: 10.1038/s41467-020-20511-7. PMID: 33431871.These authors report two Mll4 mutant mouse models that exhibited dwarfism and altered development of GHRH−neurons.Inactivating mutations in KDM6A (aka UTX) or KMT2D (aka MLL4) genes result in Kabuki syndrome (KS), whose hallmarks in...

Brief summary: A significant increase in the incidence T2D occurred in the USA during the COVID-19 pandemic, particularly among children with obesity and males.Comment: This is the first multicenter report on the incidence of T2D during the first year of the COVID-19 pandemic in the USA. The average number of new diagnoses per year in the two pre-pandemic years was 825, compared with 1463 during the first pandemic year. This increase of 77% is significan...
