How are multiple sclerosis and Tay-Sachs disease opposite one another?
Additionally, while MS can occur in anyone in the population, regardless of familial history of the disease (although first-degree relatives with MS increases your risk), in order to contract Tay-Sachs disease, both parents have to be carriers of the mutated gene which causes the disease. In those cases, the child will have a 1 in 4 chance of developing Tay-Sachs disease.
