SMA is an autosomal recessive condition that affects nerves in the spinal cord and causes muscles to get progressively weaker. There are four types of SMA with SMA type 1 being the most common and most severe. Babies with SMA type 1 have weak muscles from birth and usually do not live past two years of age. SMA types 2 and 3 are less severe than type 1 and symptoms typically develop in childhood. SMA type 4 is the mildest form and develops during adulthood. There is no cure for SMA, however treatment is aimed at managing symptoms and improving quality of life.
