About the Allied Diseases

Tay-Sachs and the allied diseases are known collectively as lysosomal storage diseases - characterized by a common biochemical defect; the inability of the body's cells to dispose of certain metabolic waste products. These waste products gradually accumulate in the cells of affected children, causing a variety of debilitating symptoms.

CATSAD has also worked with families that have children affected with conditions other than those listed below, particularly mitocondrial disorders.
