Two SMA-linked Mutations Seen to Help Identify Carriers, Allowing Better Family Counseling
Two mutations may help to improve the identification of spinal muscular atrophy (SMA) carriers – people who do not develop the disease but can pass it onto their children –, according to a recent study.
Each person has 46 chromosomes — rodlike structures where genes are located — arranged in 23 pairs, within which one chromosome is inherited from the mother and the other from the father. In genetic diseases such as SMA, the disease-causing mutations are passed from parents to their children through the genes in their chromosomes.
