Deficiency of the lysosomal enzyme beta-hexosaminidase B (beta-Hex B) (a homodimer, beta beta), caused by a defect in the HEX B gene encoding the beta-chain, is usually accompanied by an absence of beta-Hex A (a heterodimer, alpha beta), thereby causing Sandhoff disease.

Tay-Sachs and Sandhoff diseases are autosomal recessive neurodegenerative diseases resulting from the inability to catabolize GM2 ganglioside by beta-hexosaminidase A (Hex A) due to mutations of the alpha subunit (Tay-Sachs disease) or beta subunit (Sandhoff disease) of Hex A. Hex B (beta beta homodimer) is also defective in Sandhoff disease.
