Spinal Muscular Atrophy: A Short Review Article
Spinal muscular atrophy (SMA) is a genetic disorder which affect nervous system and is characterized with progressive distal motor neuron weakness. The survival motor neuron (SMN) protein level reduces in patients with SMA. Two different genes code survival motor neuron protein in human genome. Skeletal and intercostal muscles denervation lead to weakness, hypotony, hyporeflexia, respiratory fa...
متن کاملDefects in Motoneuron-Astrocyte Interactions in Spinal Muscular Atrophy.
Spinal muscular atrophy (SMA) is a motoneuron disease caused by loss or mutation in Survival of Motor Neuron 1 (SMN1) gene. Recent studies have shown that selective restoration of SMN protein in astrocytes partially alleviates pathology in an SMA mouse model, suggesting important roles for astrocytes in SMA. Addressing these underlying mechanisms may provide new therapeutic avenues to fight SMA...
متن کاملSpinal Muscular Atrophy Panel
Test code: NE1801 The Blueprint Genetics Spinal Muscular Atrophy Panel is a 27 gene test for genetic diagnostics of patients with clinical suspicion of distal hereditary motor neuropathy or spinal muscular atrophy. Spinal muscular atrophies (SMAs) are inherited in an autosomal dominant, autosomal recessive or X-linked manner. In addition to deletion or gene conversion of SMN1 and copy number va...
متن کاملSpinal muscular atrophy diagnostics.
Spinal muscular atrophy is a common autosomal recessive neuromuscular disorder caused by mutations in the survival motor neuron gene (SMN), which exists in 2 nearly identical copies (SMN1 and SMN2). Exon 7 of SMN1 is homozygously absent in about 95% of spinal muscular atrophy patients, whereas the loss of SMN2 does not cause spinal muscular atrophy. Small mutations are found in the other 5% of ...
