Cryptic splicing
WebJan 24, 2024 · Understanding pre-mRNA splicing is crucial to accurately diagnosing and treating genetic diseases. However, mutations that alter splicing can exert highly diverse effects. Of all the known types of splicing mutations, perhaps the rarest and most difficult to predict are those that activate pseudoexons, sometimes also called cryptic exons. … WebNov 1, 2003 · The latest compilation that includes cryptic 5′ss is the Aberrant Splicing Database, published in 1994, with 28 cryptic 5′ss and 15 cryptic 3′ss from different …

WebMar 17, 2024 · A major function of TAR DNA-binding protein-43 (TDP-43) is to repress the inclusion of cryptic exons during RNA splicing. One of these cryptic exons is in … WebAberrant splicing patterns were demonstrated for eight variants whose alternative transcripts were fully characterized. Different events were observed, including exon skipping, intron retention, and usage of de novo and cryptic splice sites. Transcripts with premature stop codons or in-frame loss of functionally important residues were generated.
