Comparing Tay-Sachs disease and Duchenne's muscular dystrophy?

Question

When comparing Tay-Sachs disease and Duchenne's muscular dystrophy, which of the following do both disorders have in common?

A. They both involve malfunction of the nervous system
B. They both involve mutations in which fat replaces normal tissue
C. They both lead to death in the first few years of life
D. They both are disorders that are equally distributed in the general population.

Answer 1

I believe that it would be A, because C is not right, adults with Tay, can live with it. Only Tay involves fat replacing tissue, so B is out. Tay Sachs has a prevalence of about 1 in 300 and DMD 1-3000 in males, so they don't add up.

Answer 2

you could look the two up in some excellent internet sites, such as those of Mayo sanatorium, national Institutes of well-being, CDC, or maybe internet MD. study the two ailments and then decide on your answer. until the guy responding on your question has the right medical credentials that's extremely volatile to settle for what human beings would say here. (One guy or woman wrote that Missouri is interior the midst of the barren region, and yet another wrote that the Queen Mary 2 can circulate during the Panama Canal -- the two thoroughly incorrect yet the two written with the air of authority!)
