Gene: [06p23/SCA1] ataxin 1; spinocerebellar ataxia 1 (olivopontocerebellar atrophy 1; MIM:164400); [OPCA1 ]
PAT |
The disease is characterized as the progressive cerebellum degeneration resulting in disarthria and characteristic alteration of gait. The age of manifestation varies from 20 to 50 years, death occurs usually within 10-15 years after manifestation. The large variation in such symptoms as ophthalmoplegia, dementia, reinforced reflexes, vestibular impairments, tremor, muscular clonus, weakness of distal parts, and spasticity occurs, as conserns the rate of progression and the age of manifestation. This makes the classification rather difficult." |

The next genes for spinocerebellar ataxia have been identified: SCA1 (GEM:06p23/SCA1), SCA2 (GEM:12q241/SCA2), SCA3 (GEM:14q21/MJD), SCA4 (GEM:16q221/SCA4), SCA5 (GEM:11^/SCA5), SCA6 (GEM:19p131/CACNA1A), SCA7 (GEM:03p/SCA7), and SCA8 (GEM:10q2/IOSCA)." |

[1] SCA1 is linked with D6S89; SC1 is not linked with HLA; SC1 is not linked with F13A1 (Keats-1991). [2] SCA1 is linked with HLA [>=40cM](Yakura-1974; Jackson-1977; Morton-1980; Zoghbi-1989; Rich-1987; Auburger-1990). [3] SCA1 is linked with D6S89 (Zoghbi-1989; Zoghbi-1991; Ranum-1991)." |
