{i} (Medicine) genetic disorder of lipid metabolism; hereditary disorder caused by deficiency of a vital enzyme called Hexosaminidase (occurs in east European Jewish families); lipids accumulation that affects the brain and nervous tissues resulting in death in early childhood
Recessive hereditary metabolic disorder, mostly in Ashkenazi Jews, causing progressive mental and neurologic deterioration and death by age five. A lipid, ganglioside GM2, accumulates in the brain (because of inadequate activity of the enzyme that breaks it down), with devastating neurological effects. Infants appear normal at birth but soon become listless and inattentive, lose motor abilities, and develop seizures. Blindness and general paralysis usually precede death. Tests can detect the disease in fetuses and the Tay-Sachs gene in carriers. There is no treatment
