The meaning of TAY-SACHS DISEASE is a hereditary disorder of lipid metabolism typically affecting individuals of eastern European Jewish ancestry that is marked by the accumulation of lipids especially in nerve cells of the brain due to a deficiency of h
Note: Tay-Sachs disease is inherited as an autosomal recessive trait requiring that both parents pass on a copy of the defective gene on a chromosome other than a sex chromosome. … if they both had the recessive gene and ever had a baby, there was a one in four chance the baby would...
Tay-Sachs disease (tā′săks′) n. A hereditary disease that affects young children almost exclusively of eastern European Jewish descent, in which an enzyme deficiency leads to the accumulation of gangliosides in the brain and nerve tissue, resulting in intellectual disability, convulsions, blindn...
Tay-Sachs disease is a fatal, inherited neurodegenerative disorder caused by a deficiency in the enzyme hexosaminidase-A, leading to progressive neuronal damage. This condition manifests in 3 forms: infantile, juvenile, and adult-onset, with infantile Tay-Sachs being the most severe. Symptoms typica...
Tay-Sachs disease is a hereditary neurodegenerative disorder resulting from excess storage of GM2 ganglioside within the lysosomes of cells, caused by deficiency of hexosaminidase A. The incidence of the disease is estimated to be 1 in 3,600 in Ashkenazi Jews with carrier frequency of 1 in 30 ...

Tay–Sachs disease (TSD; also known as GM2 gangliosidoses) is a family of autosomal recessive lysosomal storage diseases due to the absence or markedly deficient activity of the enzyme,β-hexosaminidase A (HEX A) and the resultant lysosomal accumulation of GM2 ganglioside, particularly in the ...
