Summaries for Spinocerebellar Ataxia, Autosomal Recessive 18

UniProtKB/Swiss-Prot : ⁷⁴ Spinocerebellar ataxia, autosomal recessive, 18: A form of spinocerebellar ataxia, a clinically and genetically heterogeneous group of cerebellar disorders. Patients show progressive incoordination of gait and often poor coordination of hands, speech and eye movements, due to degeneration of the cerebellum with variable involvement of the brainstem and spinal cord. SCAR18 features include progressive cerebellar atrophy, delayed psychomotor development, severely impaired gait, ocular movement abnormalities, and intellectual disability.

MalaCards based summary : Spinocerebellar Ataxia, Autosomal Recessive 18, is also known as scar18, and has symptoms including gait ataxia, dysdiadochokinesis and cerebellar ataxia. An important gene associated with Spinocerebellar Ataxia, Autosomal Recessive 18 is GRID2 (Glutamate Ionotropic Receptor Delta Type Subunit 2). Affiliated tissues include brain, eye and spinal cord, and related phenotypes are limb ataxia and truncal ataxia

OMIM : ⁵⁷ Autosomal recessive spinocerebellar ataxia-18 is a neurologic disorder characterized by delayed psychomotor development, severely impaired gait due to cerebellar ataxia, ocular movement abnormalities, and intellectual disability. Brain imaging shows progressive cerebellar atrophy (summary by Hills et al., 2013). (616204)
