Summaries for Spastic Ataxia 2, Autosomal Recessive

OMIM : ⁵⁷ Autosomal recessive spastic ataxia is a neurologic disorder characterized by onset in the first 2 decades of cerebellar ataxia, dysarthria, and variable spasticity of the lower limbs. Cognition is not affected (summary by Dor et al., 2014). For a discussion of genetic heterogeneity of spastic ataxia, see SPAX1 (108600). (611302)

MalaCards based summary : Spastic Ataxia 2, Autosomal Recessive, is also known as ataxia, spastic, 2, autosomal recessive, and has symptoms including cerebellar ataxia, muscular fasciculation and tremor. An important gene associated with Spastic Ataxia 2, Autosomal Recessive is KIF1C (Kinesin Family Member 1C). Related phenotypes are hypodontia and dysarthria

UniProtKB/Swiss-Prot : ⁷⁵ Spastic ataxia 2, autosomal recessive: A neurologic disorder characterized by cerebellar ataxia, dysarthria, and variable spasticity of the lower limbs. Cognition is not affected.
