C Huisman , YA Kim , S Jeon , B Shin , J Choi , SJ Lim , SM Youn , Y Park , K C M , S Kim , SK Lee , S Lee , JW Lee

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...

J Clin Endocrinol Metab. 2020;105:3203–3214. doi: 10.1210/clinem/dgaa443. PMID: 32652002The authors performed a large genome-wide association study (GWAS) to assess the role of common genetic variants in the response to GH therapy. A total of 614 children treated with GH were included: 276 with idiopathic GHD, 297 with ISS, and 41 born SGA. The findings implicate some novel mechanisms...

Int J Mol Sci. 2020 Nov 9;21(21):8403. doi: 10.3390/ijms21218403. PMID: 33182400This case report describes a patient with clinically diagnosed partial androgen insensitivity syndrome (PAIS). However, no mutation in the androgen receptor gene was identified. Instead, whole genome sequencing revealed a heterozygous point mutation inherited from the mother in the FKBP4 gene. This gene i...

Diabetes Care. 2020;43(11):e172–e173. doi: 10.2337/dc20-1633During the first phase of the COVID-19 pandemic, the DPV (the German diabetes registry database) study group asked whether or not the COVID-19 lockdown had affected the incidence of pediatric T1D in Germany (1). More than 210 German pediatric diabetes centers contributed their data on pediatric patients with T1D with an onset at ag...

Diabetes 2021 Apr;70(4):854–866. https://pubmed.ncbi.nlm.nih.gov/33431374/These authors performed a randomized trial of obese pregnant women (n=425) to investigate the effects of a pregnancy lifestyle intervention on epigenetic variations in umbilical cord blood, on neonatal body composition (DXA) and on offspring BMI in later life (up to 3 years). Offspring of mothers who re...
