RCV000151212 | SCV000199050 | uncertain significance | not specified | 2014-01-22 | criteria provided, single submitter | clinical testing | The Thr1697Ala variant in MYH6 has not been reported in individuals with cardiom yopathy or in large population studies. Computational analyses (biochemical amin o acid properties, conservation, AlignGVGD, PolyPhen2, and SIFT) do not provide strong support for or against an impact to the protein. Additional information i s needed to fully assess the clinical significance of this variant. |

RCV001850059 | SCV002266999 | uncertain significance | Hypertrophic cardiomyopathy 14 | 2024-06-11 | criteria provided, single submitter | clinical testing | This sequence change replaces threonine, which is neutral and polar, with alanine, which is neutral and non-polar, at codon 1697 of the MYH6 protein (p.Thr1697Ala). This variant is present in population databases (rs727503233, gnomAD 0.009%). 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: 164214). 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 tolerated. 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 | RCV004019815 | SCV003600725 | uncertain significance | Cardiovascular phenotype | 2022-01-19 | criteria provided, single submitter | clinical testing | The c.5089A>G (p.T1697A) alteration is located in exon 34 (coding exon 32) of the MYH6 gene. This alteration results from a A to G substitution at nucleotide position 5089, causing the threonine (T) at amino acid position 1697 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
