Spinal muscular atrophy
Spinal muscular atrophy (SMA) is a genetic disease that causes muscle weakness and progressive loss of movement.
There are several different types of spinal muscular atrophy (SMA), depending on when symptoms develop and how severe they are.
Spinal muscular atrophy (SMA) is caused by faulty genes. Most cases are passed on to a child by their parents.
Tests for spinal muscular atrophy (SMA) can be carried out before, during and after pregnancy.
Treatment and support is available to help manage the symptoms of SMA and provide the best possible quality of life. It's not currently possible to treat the underlying genetic fault that causes SMA.
