What is the life expectancy for someone with SMA?

Category: Life expectancy

Spinal muscular atrophy (SMA) life expectancy varies with the type of disease and whether or not certain treatments were received. Infants with type 0 generally do not live past birth, while adults with type 4 have a relatively normal lifespan. Children with type 1, the most common form of SMA, often do not live past 2 years old without treatment and medical support.
