Brief summary: This article shows that intra-cerebroventricular injections of a recombinant adeno-associated virus expressing MKRN3 resulted in delayed puberty in female mice.MKRN3 loss-of-function mutation is the most frequent cause of familial central precocious puberty (CPP) (1).These authors investigated the effect of MKRN3 overexpression on pubertal timing, by generating a mouse model of neonatal hypothalamic Mkrn3 ov...

To read the full abstract: J Am Soc Nephrol. 2017 Aug;28(8):2529-2539The association of hyperinsulinaemic hypoglycaemia (HH) and polycystic kidneys has not been reported before. Here, the authors studied 17 patients from 11 different families and found that all patients had a combination HH and polycystic kidneys. The HH was mild and some patients required diazoxide therapy. In contrast the poly...
