A member asked:

A neighbor child has sma (spinal muscular atrophy). is this a genetic disease?

A doctor has provided 1 answer

Yes: It's an autosomal recessive disease. That means that it takes a copy of the defective gene from each parent. Most of the time the parents of a child with SMA are carriers, meaning they only have one copy of the defective gene. It is not contagious.
