Sma phenotype

WebSMA is a group of disorders caused by degeneration of anterior horn cells and, in some subtypes, of bulbar motor neurons. Almost all cases are genetically determined, with most being autosomal recessive due to homozygous deletions of the survival motor neuron (SMN) gene on chromosome 5. WebMar 30, 2024 · Delivery of scAAV9-SMN after symptom onset had a marked impact on phenotype, electrophysiological measures, and pathology. Interpretation: High SMN levels are critical in postnatal motoneurons, and reduction of SMN results in an SMA phenotype that is SMN dependent. Importantly, clinically relevant biomarkers including CMAP and …
