NR0B1 Frameshift Mutation in a Boy with Idiopathic Central Precocious Puberty

Sex Dev. 2016;10(4):205-209. doi: 10.1159/000448726. Epub 2016 Sep 21.


NR0B1 is the causative gene for X-linked adrenal hypoplasia congenita, characterized by adrenal insufficiency, hypogonadotropic hypogonadism, and infertility. We identified an NR0B1 frameshift mutation in a boy with precocious puberty who had no signs of adrenal insufficiency. Blood examination revealed elevated testosterone levels and gonadotropin hyperresponses to gonadotropin releasing hormone (GnRH) stimulation, together with normal adrenal hormone levels. GnRH analog treatment partially ameliorated his clinical features. Molecular analysis identified a p.Glu3fsAla*16 in NR0B1. These results expand the clinical manifestations of NR0B1 mutations to include central precocious puberty without adrenal insufficiency. NR0B1 mutations likely underlie androgen overproduction via GnRH-dependent and -independent mechanisms.
