What is a SCA-12 (SPINOCEREBELLAR ATAXIA) GENE MUTATION ANALYSIS?

The SCA-12 (Spinocerebellar Ataxia) Gene Mutation Analysis test is a genetic diagnostic procedure used to detect mutations in the PPP2R2B gene, which are responsible for Spinocerebellar Ataxia type 12. This inherited neurodegenerative disorder affects coordination, balance, and movement, often presenting with tremors and progressive ataxia. Doctors order this test to confirm a suspected diagnosis, differentiate it from other ataxias, and provide genetic counseling for families. It plays a crucial role in early detection, prognosis, and guiding patient management.
