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).
