Answer 1

Answer: D. Causes an accumulation of lipids in brain cells

Step-by-step explanation:

Tay-Sachs disease is caused by a genetic mutation in the HEXA gene. It is an autosomal recessive disease that causes the mutation on an enzyme, which metabolizes GM2 Ganglioside in nerve cells, this leads to a build-up of the molecule in brain cells. At the moment there is no cure for the disease, only support treatment is available.
