Causes: Spinal muscular atrophy (SMA) is a collection of different muscle diseases. Grouped together‚ it is the second leading cause of hereditary neuromuscular disease‚ after Duchenne muscular dystrophy. Most of the time‚ a person must get the defective gene from both parents to be affected. About 4

Despite there being so many different variations‚ SCA is actually pretty rare. Even so‚ it is one of the most common causes of genetic ataxia. Even among people with no family history
