SCA2

Chr 12

ataxin 2

Also known as: ATX2, SCA2, TNRC13

The ataxin-2 protein localizes to the endoplasmic reticulum and plasma membrane where it regulates endocytosis and modulates mTOR signaling pathways that affect ribosomal translation and mitochondrial function. Pathogenic CAG repeat expansions in this gene cause spinocerebellar ataxia type 2, an autosomal dominant progressive neurodegenerative disorder affecting the cerebellum and brainstem, while intermediate-length expansions increase susceptibility to amyotrophic lateral sclerosis. The disease typically presents in adulthood with progressive cerebellar ataxia, though onset and severity correlate with repeat length.
