RCV001178392 | SCV001342830 | uncertain significance | Cardiomyopathy | 2023-09-13 | criteria provided, single submitter | clinical testing | This missense variant replaces glycine with glutamic acid at codon 800 of the MYBPC3 protein. Computational prediction is inconclusive regarding the impact of this variant on protein structure and function (internally defined REVEL score threshold 0.5 < inconclusive < 0.7, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with MYBPC3-related disorders in the literature. This variant has not been identified in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. |

Invitae | RCV002558877 | SCV003476606 | uncertain significance | Hypertrophic cardiomyopathy | 2023-10-14 | criteria provided, single submitter | clinical testing | This sequence change replaces glycine, which is neutral and non-polar, with glutamic acid, which is acidic and polar, at codon 800 of the MYBPC3 protein (p.Gly800Glu). This variant is not present in population databases (gnomAD no frequency). 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: 919921). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. 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. |
Ambry Genetics | RCV003293928 | SCV004001260 | uncertain significance | Cardiovascular phenotype | 2023-04-28 | criteria provided, single submitter | clinical testing | The p.G800E variant (also known as c.2399G>A), located in coding exon 24 of the MYBPC3 gene, results from a G to A substitution at nucleotide position 2399. The glycine at codon 800 is replaced by glutamic acid, an amino acid with similar properties. This amino acid position is conserved. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
