Summaries for Spinocerebellar Ataxia, Autosomal Recessive 13

UniProtKB/Swiss-Prot : ⁷⁶ Spinocerebellar ataxia, autosomal recessive, 13: Spinocerebellar ataxia is 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. SCAR13 is characterized by delayed psychomotor development beginning in infancy. Affected individuals show mild to profound mental retardation with poor or absent speech as well as gait and stance ataxia and hyperreflexia.

MalaCards based summary : Spinocerebellar Ataxia, Autosomal Recessive 13, also known as scar13, is related to ataxia and polyneuropathy, adult-onset, and has symptoms including dysdiadochokinesis An important gene associated with Spinocerebellar Ataxia, Autosomal Recessive 13 is GRM1 (Glutamate Metabotropic Receptor 1). Affiliated tissues include eye, brain and spinal cord, and related phenotypes are intellectual disability and hyperreflexia

OMIM : ⁵⁸ Autosomal recessive spinocerebellar ataxia-13 is an autosomal recessive neurologic disorder characterized by delayed psychomotor development beginning in infancy. Affected individuals show mild to profound mental retardation with poor or absent speech as well as gait and stance ataxia and hyperreflexia. Most individuals also have eye movement abnormalities. Brain MRI shows cerebellar atrophy and ventriculomegaly (summary by Guergueltcheva et al., 2012). (614831)
