In recent years, we have seen great advances in the elucidation of genetic causes of cerebellar ataxia, with newly identified genes regulating a wide spectrum of cellular functions, including intracellular signaling, tau regulation, and mitochondrial function.1 However, a genetic defect cannot be found in approximately 40% of patients with ataxia,1 including those in whom ataxia is associated with reproductive endocrine failure, a syndrome first reported by Gordon Holmes in 1908.2 Most patients with this syndrome have a hypogonadotropic condition, with defective secretion of gonadotropins by the pituitary gland.3-12 Strikingly, genes associated with ataxia have little functional overlap with genes associated with hypogonadotropic hypogonadism, which encode proteins involved in the biologic function of the neurons that secrete gonadotropin-releasing hormone (GnRH).13A decade ago, we described a consanguineous family with a syndrome of cerebellar ataxia, dementia, and hypogonadotropic hypogonadism.12 Here we report the results of whole-exome and targeted sequencing performed to identify mutations that underlie the syndrome in this kindred and in unrelated patients.
