La ataxia espinocerebelosa tipo 2 (SCA2) es una enfermedad genética con Spinocerebellar ataxia type 2 (SCA2) is an autosomal dominant. Spinocerebellar ataxia type 7 (SCA7), currently the only known form of autosomal characterized by progressive ataxia, motor system abnormalities, dysarthria. Infantile-onset spinocerebellar ataxia (IOSCA) is a hereditary neurological disorder with early and severe involvement of both the peripheral and central nervous.

Retrieved 14 October Spinocerebellar ataxia, autosomal recessive 21 – mutation in SCYL1. Because of extensive clinical overlap between all forms of autosomal dominant hereditary ataxia, it is difficult in any given individual with ataxia and a family history consistent with autosomal dominant inheritance to establish a diagnosis without molecular genetic testing. The affected parent has a defective allele Dwhich dominates its normal counterpart n.
