WebJun 2, 2024 · Genetic variants in MYBPC3 are one of the most common causes of hypertrophic cardiomyopathy (HCM). While variants in MYBPC3 affecting canonical splice site dinucleotides are a well-characterised cause of HCM, only recently has work begun to investigate the pathogenicity of more deeply intronic variants. Here, we present three … WebFeb 1, 2024 · Intron recognition by the spliceosome mainly depends on conserved intronic sequences such as 5' splice sites, 3' splice sites, and branch sites. Therefore, even substitution of just a single nucleotide in a 5' or 3' splice site abolishes the splicing at the mutated site and leads to cryptic splice site usage.
