What types of spinal muscular atrophy there are?
Type 0
The disease is typically fatal between 2 and 6 months of age. These infants do not develop any motor skills expected of infants their age.
Type I

This type of SMA is usually fatal within two years. With mechanical breathing aids, children with type I SMA may live longer. There are a few known cases of SMA type I in which the child survived to adolescence or adulthood.

Type II
With type II SMA, 75% of those affected live to the age of 25. They are often able to sit independently when placed in a sitting position, but lose this ability by their mid-teens.

Type III
People with type III SMA may live a normal lifespan. Many learn to walk independently, though most lose the ability to do so by their 30s or 40s.

Type IV
A normal lifespan is possible for people with type IV SMA. They do not develop symptoms until their 20s or 30s and usually retain the ability to walk independently.
