WebSpinal muscular atrophy (SMA) is an autosomal recessive neuromuscular disorder caused by deletions or mutations of the SMN1 gene located on chromosome 5q. It is caused by a genetic defect in the SMN survival motor neuron gene. The copy number of the SMN2 gene varies between patients and determines the clinical phenotype of the disease. WebApr 27, 2012 · The potential broad range of SMA phenotype that is predicted by loss of SMN1 is focused to some extent by characterization of SMN2 copy number, but within each specific SMN2 genotype there is broad spectrum of motor function, and over time the severity of motor impairment can vary even more.

With the development of the contractile machinery in SMCs, increasing numbers of contraction-specific proteins are expressed. Remarkably, SMA is expressed in all SMCs independently of the functional phenotype and is therefore used as a general marker of …

WebThe SMA phenotype is determined, at least in part, by the number of copies of the centromeric copy of the SMN gene, known as SMN2; patients with milder phenotypes tend to have more copies of SMN2.
