Sma1 genetic disease
WebbThis gene may be a modifier of disease caused by mutation in the telomeric copy. The critical sequence difference between the two genes is a single nucleotide in exon 7, which is thought to be an exon splice enhancer. Note that the nine exons of both the telomeric and centromeric copies are designated historically as exon 1, 2a, 2b, and 3-8. WebbDisease severity is modified by the number of SMN2 copies, a backup gene, which produces a small fraction of functional SMN protein; fewer copies of SMN2 correlate with more severe disease . The majority of infants with SMA type 1 …
