Cryptic splice site mutation
WebIn addition, DNA sequence changes may have unforeseen effects, impairing gene function through other mechanisms such as influencing RNA stability or splicing (disrupting an exonic splice enhancer, activating a cryptic splice site or creating a new splice site). WebJul 26, 2024 · This is the first report of a cryptic splice site within the coding region of COL1A2. which results in abnormal splicing causing OI. The experience from this case demonstrates that routine diagnostic approaches may miss cryptic splicing mutations in causative genes due to the lack of universally applicable algorithms for splice-site …

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. WebMutations in the DMD gene most commonly involve single- or multi-exon deletions that disrupt the open reading frame (ORF) and introduce a premature stop codon that results in the production of a nonfunctional truncated dystrophin protein and causes a severe muscle degeneration phenotype ( 3 ).
