| Ambry Genetics | RCV002452438 | SCV002613758 | uncertain significance | Cardiovascular phenotype | 2022-10-30 | criteria provided, single submitter | clinical testing | The p.R1214Q variant (also known as c.3641G>A), located in coding exon 24 of the MYH6 gene, results from a G to A substitution at nucleotide position 3641. The arginine at codon 1214 is replaced by glutamine, an amino acid with highly 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. |

RCV003514556 | SCV004275840 | uncertain significance | Hypertrophic cardiomyopathy 14 | 2024-08-08 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 1214 of the MYH6 protein (p.Arg1214Gln). This variant is present in population databases (rs778007219, gnomAD 0.003%). This variant has not been reported in the literature in individuals affected with MYH6-related conditions. ClinVar contains an entry for this variant (Variation ID: 1733518). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt MYH6 protein function with a positive predictive value of 80%. 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. |
