Cryptic splice site

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 ...
