Boucher-neuhauser Syndrome; Bnhs

Description

Boucher-Neuhauser syndrome is an autosomal recessive disorder characterized classically by the triad of spinocerebellar ataxia, hypogonadotropic hypogonadism, and visual impairment due to chorioretinal dystrophy. The age at onset is variable, but most patients develop one or more symptoms in the first decade of life. Chorioretinal dystrophy may not always be present. BNHS is part of a spectrum of neurodegenerative diseases associated with mutations in the PNPLA6 gene that also includes spastic paraplegia-39 (SPG39 ) (summary by Synofzik et al., 2014).See also Gordon Holmes syndrome (GDHS ), caused by mutation in the RNF216 gene (OMIM ), which is also characterized by the combination of cerebellar ataxia and hypogonadotropic hypogonadism.
