Description

This sequence change creates a premature translational stop signal (p.Trp1098*) in the MYBPC3 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in MYBPC3 are known to be pathogenic (PMID: 19574547). This variant is not present in population databases (gnomAD no frequency). This premature translational stop signal has been observed in individuals with hypertrophic cardiomyopathy (PMID: 20624503, 23233322, 25031304, 31006259). ClinVar contains an entry for this variant (Variation ID: 520341). For these reasons, this variant has been classified as Pathogenic.
