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)
