GM2 ganglioside activator, also known as GM2A, is a human gene.

section_title =
summary_text = The protein encoded by this gene is a small glycolipid transport protein which acts as a substrate specific co-factor for the lysosomal enzyme beta-hexosaminidase A. Beta-hexosaminidase A, together with GM2 ganglioside activator, catalyzes the degradation of the ganglioside GM2, and other molecules containing terminal N-acetyl hexosamines. Mutations in this gene result in GM2-gangliosidosis type AB or the AB variant of Tay-Sachs disease.cite web | title = Entrez Gene: GM2A GM2 ganglioside activator| url =| accessdate = ]
