Summaries for Spastic Ataxia 3, Autosomal Recessive

UniProtKB/Swiss-Prot : 73 Spastic ataxia 3, autosomal recessive: A neurologic disorder characterized by cerebellar ataxia, ataxic gait, spasticity, and hyperreflexia. Other variable features include dysarthria, dysmetria, mild cognitive impairment, urinary urgency and dystonic positioning.

MalaCards based summary : Spastic Ataxia 3, Autosomal Recessive, also known as ataxia, spastic, 3, autosomal recessive, is related to leigh syndrome and spastic ataxia, charlevoix-saguenay type, and has symptoms including gait ataxia, muscle spasticity and cerebellar ataxia. An important gene associated with Spastic Ataxia 3, Autosomal Recessive is MARS2 (Methionyl-TRNA Synthetase 2, Mitochondrial). Related phenotypes are hyperreflexia and cerebellar hypoplasia
