Summaries for Testotoxicosis

NIH Rare Diseases : 54 Testotoxicosis is a form of gonadotropin-independent precocious puberty in which boys experience early onset and progression of puberty. The disease generally presents between 2 and 4 years of age. Patients have accelerated growth, early development of secondary sexual characteristics and reduced adult height. Testotoxicosis is caused by an activating mutation of the luteinizing hormone receptor (LHCGR) gene, which leads to increased levels of sex steroids in the context of low luteinizing hormone. The condition may be sporadic or transmitted as a dominant trait. It is only expressed in males. Treatment consists of reducing hyperandrogenism in children (sexual maturation, stature), with ketoconazole or a combination of antiandrogens and aromatase inhibitors.

MalaCards based summary : Testotoxicosis, also known as familial testotoxicosis, is related to precocious puberty, male-limited and precocious puberty. An important gene associated with Testotoxicosis is LHCGR (Luteinizing Hormone/Choriogonadotropin Receptor), and among its related pathways/superpathways are Calcium signaling pathway and G alpha (s) signalling events. The drugs Anastrozole and Bicalutamide have been mentioned in the context of this disorder. Affiliated tissues include pituitary, and related phenotypes are adipose tissue and endocrine/exocrine gland
