Sandhoff disease is closely related to Tay-Sachs disease. It is a lysosomal storage disorder, but is much less common than Tay-Sachs disease.The fatty material (GM2 ganglioside) which accumulates in the child's brain cells is the same in Sandhoff and Tay-Sachs diseases.

What makes Sandhoff distinct from Tay-Sachs?

The enzyme deficiency in Sandhoff Disease arises from mutations in a different gene on a different chromosome (i.e. the b-subunit gene on chromosome 5 instead of the a-subunit gene on chromosome 13 for Tay-Sachs). As a result, children with Sandhoff Disease have almost no hexosaminidase at all, unlike children with Tay-Sachs who still have Hex-B activity but not Hex-A. Children affected by Sandhoff's disease may show more marked involvement of the bones and abdominal organs.

Carrier Population

Unlike Tay-Sachs disease, Sandhoff disease occurs more commonly in the non-Jewish population.
