WebJun 18, 2007 · Mutation-induced aberrant splice sites found in disease genes often involve disruption of the consensus sequence of the authentic sites, while activating a cryptic splice site nearby. However, aberrant splice sites can also be generated by mutations that create splice-site consensus sequences. WebA total of 25 variants were identified spliceogenic, either causing/enhancing exon skipping or activation of cryptic splice sites, or both. Except from a single intronic variant causing minor effects on BRCA1 pre-mRNA processing in our analyses, 23 out of 24 intronic variants were correctly predicted by MaxEntScan, while HSF was less accurate ... WebApr 1, 2009 · Since a mutation can result not only in the disruption of a 5′ss or a 3′ss, but also in the creation of a new splice site, HSF evaluates the ‘creation of cryptic splice sites’.
