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.
Most cases of Boucher-Neuhäuser syndrome are caused by mutations in the PNPLA6 gene. Such mutations are the only known cause of the condition. Researchers speculate that as-yet-unidentified mutations in the PNPLA6 gene or changes in other genes are involved in the remainder of cases.
Boucher-Neuhäuser syndrome is a rare condition. Its prevalence is unknown.
This condition is inherited in an autosomal recessive pattern, which means both copies of the gene in each cell have mutations. The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition.
