About GM2A

Cytogenetic location: 5q33.1 Genomic coordinates (GRCh38): 5:151,253,185-151,270,440 (from NCBI)

This gene has 3 transcripts (splice variants), 205 orthologues and is associated with 3 phenotypes. Ubiquitous expression in skin (RPKM 39.8), placenta (RPKM 38.5) and 24 other tissues.

Summary

This gene encodes 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. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Nov 2009]
