The GBA gene encodes an enzyme known as acid beta-glucocerebrosidase or beta-glucosidase, a lysosomal enzyme that catalyzes the breakdown of a fatty waste product called glucocerebroside. Medically, the primary relevance of the GBA gene comes about from what happens when it's inactive. Specifically, having too little glucocerebrosidase results in the build-up of glucocerebroside, mostly in the liver and spleen and to a lesser extent in the bones, lungs and other organs.
Clinically, variation in the GBA gene has been linked to Gaucher disease, Parkinson's disease, and Lewy body dementia. In brief:
- Gaucher disease
- Over 200 variants in the GBA gene have been linked to one or more of the 3 types of Gaucher disease.
- Inheritance is recessive, so two inactive GBA alleles must be inherited to be affected.
- Among Ashkenazi Jews, the carrier frequency for GBA mutation may be about 1 in 15.
- Parkinson's disease
- Mutations in the GBA gene are the common genetic risk factor known to date.
- Carriers of a single GBA mutation are at ~5 fold higher risk for Parkinson's disease.
- Carriers of a single neuropathic GBA mutation are at ~3 fold higher risk for cognitive impairment/decline [PMID 27717005]
