Spinal muscular atrophy (SMA) is a genetic, motor neuron disease caused by progressive degeneration of motor neurons in the spinal cord. The disorder causes weakness and wasting of the voluntary muscles. Weakness is often more severe in the legs than in the arms. The childhood SMAs are all autosomal recessive diseases. This means that they run in families and more than one case is likely to occur in siblings or cousins of the same generation. Parents usually have no symptoms, but still carry the gene. The gene for SMA has been identified and accurate diagnostic tests exist. There are many types of SMA; some of the more common types are described below.
