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). 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 ).

WebMay 12, 2024 · Two recent studies of small cohorts of mutation-negative cases (46 5 and 93 6 probands) described 8 novel cryptic splice-altering variants in MYBPC3, with a prevalence of 9% and 6.5%, respectively. In our study, the prevalence was only 2.2% in otherwise mutation-negative patients. 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 ... green chef contact us uk
