Summaries for Boucher-Neuhauser Syndrome

OMIM : 53 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; 612020) (summary by Synofzik et al., 2014). See also Gordon Holmes syndrome (GDHS; 212840), caused by mutation in the RNF216 gene (609948), which is also characterized by the combination of cerebellar ataxia and hypogonadotropic hypogonadism. (215470)

MalaCards based summary : Boucher-Neuhauser Syndrome, also known as spinocerebellar ataxia, hypogonadotropic hypogonadism, and chorioretinal dystrophy, is related to ataxia - hypogonadism - choroidal dystrophy and megalocornea-mental retardation syndrome, and has symptoms including ataxia, hypogonadotrophic hypogonadism and scanning speech. An important gene associated with Boucher-Neuhauser Syndrome is PNPLA6 (Patatin Like Phospholipase Domain Containing 6). Affiliated tissues include neutrophil.

UniProtKB/Swiss-Prot : 71 Boucher-Neuhauser syndrome: 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.

Genetics Home Reference : 24 Boucher-Neuhäuser syndrome is a rare disorder that affects movement, vision, and sexual development. It is part of a continuous spectrum of neurological conditions, known as PNPLA6-related disorders, that share a genetic cause and have a combination of overlapping features. Boucher-Neuhäuser syndrome is characterized by three specific features: ataxia, hypogonadotropic hypogonadism, and chorioretinal dystrophy.
