All you need to know about: Spinal Muscular Atrophy
Spinal Muscular Atrophy (SMA) is a rare genetic neuromuscular disorder caused by the loss of motor neurons. The article explains the genetic basis of the disease, its classification into five types, and the importance of early intervention.
Spinal muscular atrophy (SMA) is a rare inherited neuromuscular disorder characterised by the progressive loss of lower motor neurons -- specialised nerve cells in the spinal cord and brainstem that control voluntary muscle movement.
