About 95% of people with SMA have a deletion mutation in both copies of the SMN1 gene. This is called a homozygous deletion. The other 5% of people with SMA have a âpoint mutation â. This is when a single base (nucleotide) within the DNA is altered. Often they will have the more common deletion mutation in one of their copies of SMN1, and the point mutation in the other copy.
