Summaries for Spinocerebellar Ataxia, X-Linked 3

NIH Rare Diseases : 53 The following summary is from Orphanet, a European reference portal for information on rare diseases and orphan drugs.Orpha Number: 85297Disease definitionX-linked spinocerebellar ataxia type 3 is a form of spinocerebellar degeneration characterized by onset in infancy of hypotonia, ataxia, sensorineural deafness, developmental delay, esotropia, and optic atrophy, and by a progressive course leading to death in childhood. It has been described one family with at least six affected males from five different sibships (connected through carrier females). It is transmitted as an X-linked recessivetrait.Visit the Orphanet disease page for more resources.
