SMA is a disease that's passed down through families. If your child has SMA, it's because he's got two copies of a broken gene, one from each parent. When this happens, his body won't be able to make a specific kind of protein. Without it, the cells that control muscles die. If your child gets a faulty gene from just one of you, he won't get SMA but will be a carrier of the disease. When your child grows up he could pass the broken gene to his child.
