Summaries for Spastic Ataxia 1, Autosomal Dominant

OMIM : 57 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). (108600)

MalaCards based summary : Spastic Ataxia 1, Autosomal Dominant, also known as ataxia, spastic, 1, autosomal dominant, is related to spastic ataxia 2, autosomal recessive and spastic ataxia 5, autosomal recessive, and has symptoms including memory loss and cerebellar ataxia. An important gene associated with Spastic Ataxia 1, Autosomal Dominant is VAMP1 (Vesicle Associated Membrane Protein 1). Affiliated tissues include eye, and related phenotypes are ptosis and tremor

UniProtKB/Swiss-Prot : 75 Spastic ataxia 1, autosomal dominant: An autosomal dominant form of spastic ataxia, a progressive neurodegenerative disorder characterized by lower-limb spasticity and generalized ataxia with dysarthria, impaired ocular movements, and gait disturbance.
