What Does SMA Stand For?

SMA stands for Spinal Muscular Atrophy

Spinal Muscular Atrophy (SMA) is a genetic disorder characterized by the progressive degeneration of motor neurons in the spinal cord, leading to muscle weakness and atrophy. It is primarily caused by mutations in the SMN1 gene, which plays a crucial role in the survival of motor neurons. SMA affects individuals across various age groups and can range from mild to severe forms, impacting mobility and respiratory function. Early diagnosis and advancements in treatment options have improved outcomes for those affected by this condition.
