WebMay 26, 2024 · We define cryptic splicing as the emergence or relative increase in splice junctions that splice from known splice sites to unannotated positions within introns. … WebAug 6, 2024 · An intron is a stretch of DNA that begins and ends with a specific series of nucleotides. These sequences act as the boundary between introns and exons and are known as splice sites. The recognition of the boundary between coding and non-coding DNA is crucial for the creation of functioning genes.
WebMay 25, 2024 · Cryptic splice sites identified in the EJC LOF datasets can be found within sequences that are normally exonic or intronic. These sites and the putative de novo intron are shown as red text and dashed lines. Bottom: Pie chart indicating the distribution of different splice junction classes. A splice site mutation is a genetic mutation that inserts, deletes or changes a number of nucleotides in the specific site at which splicing takes place during the processing of precursor messenger RNA into mature messenger RNA. Splice site consensus sequences that drive exon recognition are located at the very termini of introns. The deletion of the splicing site results in one or more introns remai…
WebMar 15, 2001 · Interestingly, in 4.8% of mRNAs, the last nucleotide of exon 4, a G, is used in combination with the mutated G→T as a new GT donor site, corresponding to a 1-bp deletion in the transcript. Two other cryptic splice sites, 3135-3136 GT and 3165-3166 GT situated in exon 4 (numbering according to Genbank accession number M64982) are …
