Abstract
The spinal muscular strophies (SMA) of childhood are inherited neurodegenerative disorders in which there is progressive weakness and wasting of skeletal muscle secondary to degeneration of the anterior horn cells in the spinal cord and brain stem nuclei.1 SMA is the second most common serious neuromuscular disease of childhood, affecting one in 10,000 children.2 SMA of childhood is clinically and genetically a heterogeneous group. Their etiologies are currently unknown, and no specific treatment is available.3
