WebSpinal muscular atrophy (SMA) is one of the major genetic disorders associated with infant mortality. More than 90% cases of SMA result from deletions or mutations of Survival Motor Neuron 1 (SMN1) gene. SMN2, a nearly identical copy of SMN1, does not compensate for the loss of SMN1 due to predominant skipping of exon 7. WebThis lesion completely abolishes use of this splice site, activates two cryptic splice sites, and alters the splicing pattern from extant splice sites. One activated donor site, located nine nt 5' to the normal splice donor site, begins with the dinucleotide GC.

WebMar 15, 2024 · In humans, splicing involves a series of reactions catalyzed by a large ribonucleoprotein complex called the spliceosome, which recognizes key regulatory sequences on the pre-mRNA. The two bases at each extremity of the intron constitute the canonical donor (GU) and acceptor (AG) splice sites. WebApr 24, 2024 · Overall, SpliceAI predicts about 7-fold more cryptic splice site variants than the other two approaches because it is not limited to specific nucleotides (e.g. D+5), includes splice sites further from the exons, and evaluates each splice site individually. Considering variants assessed consistently between these three methods, SpliceAI …
