Spinocerebellar Ataxia-21 in a Turkish Child

Hereditary cerebellar ataxias are genetically heterogeneous disorders. Autosomal recessive spinocerebellar ataxia-21 (SCAR21) is a neurologic disorder characterized by the onset of cerebellar ataxia, recurrent episodes of liver failure, peripheral neuropathy, and learning disabilities. Herein, we reported a case presented with gait and balance problems, swallowing difficulties, mild delayed motor development, and mild learning disability with SCAR21 that confirmed by mutation analysis in a Turkish child. To the best of our knowledge, this is the first case of SCAR21 from Turkey.
