WebThis mutation weakens a branch site and activates a cryptic acceptor splice site, causing the insertion of 14 intronic nucleotides into the mRNA. Conclusion: We found three different mutations, one exonic, one in a donor splice site and one intronic, that all caused missplicing of pre-mRNA. We analyzed these mutations with four different splice ... 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.
