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...

Brief Summary: This study investigated congenital hypothyroidism (CH) due to dominantly inherited resistance to TSH (RTSH) in 12 unrelated families. It reveals that mutations in a non-coding (TTTG) short tandem repeat (STR) on chromosome 15q cause this condition by activating a thyroid-specific enhancer cluster. Functional studies showed that activation of this enhancer cluster leads to upregulation of the bicistronic MIR7-2/MIR1179 locus, resulting in overexpression of its mi...
