Spastic Ataxia 1, Autosomal Dominant; Spax1

Description

Hereditary spastic ataxia comprises a heterogeneous group of progressive neurodegenerative disorders characterized by lower-limb spasticity and generalized ataxia with dysarthria, impaired ocular movements, and gait disturbance. Spastic ataxia-1 (SPAX1) is an autosomal dominant form of the disorder with linkage to chromosome 12p13 (summary by Meijer et al., 2002). Genetic Heterogeneity of Spastic AtaxiaSee also SPAX2 (OMIM ), caused by mutation in the KIF1C gene (OMIM ) on chromosome 17p13; SPAX3 (OMIM ), caused by rearrangements of the MARS2 gene (OMIM ) on chromosome 2q33; SPAX4 (OMIM ), caused by mutation in the MTPAP gene (OMIM ) on chromosome 10p11; SPAX5 (OMIM ), caused by mutation in the AFG3L2 gene (OMIM ) on chromosome 18p11; SPAX6 (OMIM ), caused by mutation in the SACS gene (OMIM ) on chromosome 13q12; SPAX7 (OMIM ); and SPAX8 (OMIM ), caused by mutation in the NKX6-2 gene (OMIM ) on chromosome 8q21.
