Description | A very rare gonadotropin-independent familial form of male-limited precocious puberty generally presenting between 2-5 years of age as accelerated growth, early development of secondary sexual characteristics and reduced adult height. Caused by an activating mutation of the Lutropin-Choriogonadotropic Hormone Receptor gene (LHCGR, 2p21) which leads to increased levels of sex steroids in the context of low luteinising hormone. This receptor's chronic activation leads to precocious testosterone production by Leydig cells. No effect is observed in female carriers due to the dual luteinising hormone (LH)/ follicle stimulating hormone (FSH) signal necessary to promote ovarian stimulation. Transmission is autosomal dominant. Mothers may act as silent carriers, with each son having a 50% chance of displaying this disorder. |
