Incidence of spinal muscular atrophy

WebSpinal muscular atrophies (SMA) are a group of genetic (passed down by parents) diseases that affect motor neurons (nerve cells) in the spinal cord, causing the weakening of voluntary muscles (muscles that you control). This may affect crawling, walking, swallowing, breathing, and other functions. Intellectual development is normal in SMA. WebSpinal muscular atrophy (SMA) is an autosomal-recessive disease that affects motor neurons in the anterior horn. It is a common genetic cause of early infant mortality with an incidence of 1:10,000, caused by homozygous disruption of the survival motor neuron 1 (SMN1) gene by mutation, deletion or conversion.
