RESUMEN
Spinocerebellar ataxias are a high clinically and genetically heterogeneous group of neurodegenerative disorders, usually belongs to autosomal dominant hereditary cerebellar ataxia. Spinocerebellar ataxia type 5 (SCA5) is one of the extremely rare subtypes and caused by heterozygous mutation of SPTBN2 gene. A case of infant-onset SCA5 patient is reported, mainly manifested as global developmental delay, ataxia and dysarthria, carrying the heterozygous missense variant c.1438C>T (p. Arg480Trp) in the SPTBN2 gene. This mutation may have an important impact on functional regions of the β-Ⅲ spectrin, leading to the occurrence of disease.
