Mondo Description Ataxia-hypogonadism-choroidal dystrophy syndrome is a very rare autosomal recessive, slowly progressive neurodegenerative disorder characterized by the triad of cerebellar ataxia (that generally manifests at adolescence or early adulthood), chorioretinal dystrophy, which may have a later onset (up to the fifth-sixth decade) leading to variable degrees of visual impairment, and hypogonadotropic hypogonadism (delayed puberty and lack of secondary sex characteristics). Ataxia-hypogonadism-choroidal dystrophy syndrome belongs to a clinical continuum of neurodegenerative disorders along with the clinically overlapping cerebellar ataxia-hypogonadism syndrome.

Uniprot Description An autosomal recessive disorder characterized by spinocerebellar ataxia, hypogonadotropic hypogonadism, and visual impairment due to chorioretinal dystrophy. The age at onset is variable, but most patients develop 1 or more symptoms in the first decade of life. Chorioretinal dystrophy may not always be present.
