WebJul 18, 2024 · Cryptic exons were initially classified based on novelty in annotation, but as the comprehensiveness of transcript annotation improves, the number of novel exons will shrink. Cassette exons with a PSI < 10% in controls and a dPSI > 10% were considered cryptic exons. 101 exons met these criteria, of which 49 were not annotated by … WebMar 17, 2024 · Cryptic exons contain parts of introns that are erroneously spliced into the pre-mRNA. Incorporation of cryptic exons may destabilize mRNAs leading to their degradation or alter the reading frame causing the generation of aberrant proteins [ 8 – 13 ].
