Part Descriptions
LP30742-8 HEXA gene
The HEXA gene is located on chromosome 15q23 and encodes the alpha subunit of beta-hexosaminidase, which is responsible for the degradation of GM2 gangliosides and other molecules containing terminal N-acetyl hexosamines. Beta-hexosaminidase is composed of two subunits, alpha and beta, which are encoded by the genes HEXA and HEXB, respectively. Mutations in both HEXA and HEXB lead to an accumulation of GM2 gangliosides in neurons result in neurodegenerative disorders termed the GM2 gangliosidoses. HEXA mutations are associated with Tay-Sachs disease (GM2-gangliosidosis type I), and HEXB mutations are associated with Sandhoff disease (GM2-gangliosidosis type II). In their classic forms, Tay-Sachs and Sandhoff diseases are clinically indistinguishable and are characterized by the onset of progressive neurodegeneration in infancy, followed by paralysis, dementia, and death by age 3.

LP30742-8 HEXA gene
The HEXA gene (hexosaminidase A (alpha polypeptide)) [HGNC Gene ID:4878] is located on chromosome 15q24.1. This gene encodes the alpha subunit of the lysosomal enzyme beta-hexosaminidase that, together with the cofactor GM2 activator protein, catalyzes the degradation of the ganglioside GM2, and other molecules containing terminal N-acetyl hexosamines. Beta-hexosaminidase is composed of two subunits, alpha and beta, which are encoded by separate genes. Both beta-hexosaminidase alpha and beta subunits are members of family 20 of glycosyl hydrolases. Mutations in the alpha or beta subunit genes lead to an accumulation of GM2 ganglioside in neurons and neurodegenerative disorders termed the GM2 gangliosidoses. Alpha subunit gene mutations lead to Tay-Sachs disease (GM2-gangliosidosis type I). [provided by RefSeq, Jul 2009] [NCBI Gene ID:3073]
