WebSome splice-site mutations have an intermediate effect upon splicing that permits the production of a low level of properly spliced mRNA. An excellent example is the 3849 + 10kbC → T mutation. This mutation activates a cryptic splice donor site in intron 19 causing the inclusion of a novel 84 basepair exon into CFTR mRNA transcripts (45). Eukaryotic genomes contain large numbers of splice sites, known as cryptic splice sites (css), which are generally held to be disadvantageous sites that are dormant or used only at low levels unless activated by mutation of nearby authentic or advantageous splice sites (1,2). Once activated, css may be used … See more The CSF program is designed to identify transcripts that are generated through the low level use of css by normal genes.
