Clinical Trials on narcolepsy 1. Patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional. There is no known cure for spinocerebellar ataxia (SCA). The best treatment options for SCA vary by type and often depend on the signs and symptoms present in each person. The disorder shows an autosomal recessive mode of inheritance, and affected individuals are usually euthanized by one year of age on welfare grounds due to an inability to ambulate. Ataxia in SCAs is often adult-onset and gradually progressive; spinocerebellar ataxia type 29 (SCA29 [MIM 117360]) is … ITPR1is the only geneknown to be associated with SCA15. Studies indicate that ITPR1 gene mutations that cause the spinocerebellar ataxias affect different regions of the protein than do the mutations that cause Gillespie syndrome.
