Hypogonadotropic hypogonadism in a female patient previously diagnosed as having waardenburg syndrome due to a sox10 mutation

Hypogonadotropic hypogonadism (HH) is a clinically and genetically heterogeneous condition that can be associated with several additional clinical features such as anosmia, cleft palate, and hearing loss . HH with anosmia is referred to as Kallmann syndrome (KS). More than 20 genes are known to underlie HH and/or KS, although mutations in these genes account for only a minor portion of the etiology of HH/KS [1, 2, 3, 4]. In 2013, Pingault et al. identified SOX10 mutations in seven patients with KS . Furthermore, Pingault et al. found that genetic knockout of Sox10 disrupted migration of GnRH cells in murine fetuses . Subsequently, Vaaralahti et al. identified an additional KS patient with a SOX10 mutation . These results indicate that SOX10 mutations constitute rare genetic causes of KS. Currently, SOX10is known as one of the causative genes of Waardenburg syndrome (WS), a rare genetic disorder characterized by hearing loss and hypopigmentation in the skin,...
