Invitae | RCV000703559 | SCV000832463 | uncertain significance | Hypertrophic cardiomyopathy | 2023-10-22 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 306 of the MYBPC3 protein (p.Arg306Trp). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This variant has not been reported in the literature in individuals affected with MYBPC3-related conditions. ClinVar contains an entry for this variant (Variation ID: 580112). An algorithm developed specifically for the MYBPC3 gene suggests that this missense change is likely to be tolerated (PMID: 21310275). This variant disrupts the p.Arg306 amino acid residue in MYBPC3. Other variant(s) that disrupt this residue have been observed in individuals with MYBPC3-related conditions (PMID: 27532257), which suggests that this may be a clinically significant amino acid residue. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. |
