| 616127 | OMIM | Spinocerebellar ataxia, autosomal recessive, 17 (SCAR17) | 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. SCAR17 features include non-progressive congenital cerebellar ataxia, mildly delayed walking with an unsteady gait and frequent falls, dysarthria, dysmetria, hypotonia in the extremities, truncal ataxia, increased reflexes in the lower extremities, and intellectual disability. The disease is caused by variants affecting the gene represented in this entry. A disease-causing mutation has been reported that affects an intronic splice donor site and causes exon 9 skipping, this leads to an out-of-frame stop codon after 60 aberrant amino acids. Patients carrying this mutation exhibit much lower mRNA and protein levels compared to unaffected controls, probably due to mRNA nonsense-mediated decay (PubMed:25361784). |
