WebApr 5, 2024 · Interestingly, although a majority of fusions utilize existing exon/intron structure by connecting them to form chimeric proteins, cryptic exons are created in ~3% fusion-positive patients. The requirement of proper splicing sites and translation frames in these fusions may explain their relatively low prevalence. WebFigure 8 shows a range of possible outcomes of blocking an internal exon, including exon skipping (the most common outcome), intron insertion, and the products of cryptic splice site activation, partial exon deletion and partial intron insertion.
