Abstract
The residual hexosaminidase isozymes (hex) in juvenile Sandhoff and infantile Sandhoff disease fibroblasts, were determined by starch gel electrophoresis and column isoelectric focusing. Hex A and hex S are the major residual isozymes in fibroblasts from the juvenile patient, while hex B is barely detectable. Only hex S could be detected in fibroblasts from infantile Sandhoff patients. The defects in juvenile and infantile Sandhoff disease may be different allelic modifications of the .beta. subunit common to hex A and hex B.
