Question

Quizplus · Accepted Answer

Tay-Sachs disease is a genetic disorder that causes an accumulation of a particular lipid called GM2 ganglioside in brain cells. This buildup ultimately leads to the destruction of the affected cells, causing neurological symptoms and early death.

B, C, and D are incorrect because Tay-Sachs disease does not involve damage to liver cells, or a deficiency in the enzymes that digest polysaccharides or glycogen.
