RCV000584763 | SCV000692495 | uncertain significance | Hypertrophic cardiomyopathy 1 | 2017-03-09 | criteria provided, single submitter | research | The MYH7 Gly1057Asp is absent from both the 1000 genomes project (http://www.1000genomes.org/), as well as the Exome Aggregation Consortium dataset (http://exac.broadinstitute.org/). We identified this variant in 1 HCM proband (Ingles J, et al., 2005). The proband has no family history of HCM or SCD. Interestingly, a different rare missense variant at this amino acid position (Gly1057Ser) has also been reported in HCM individuals, suggesting that an amino acid substitution at this site may not be tolerated. Computational tools SIFT, MutationTaster PolyPhen-2 and, PolyPhen-HCM predict this variant to have a deleterious effect. Based on rarity in populations and our limited familial data we have classified MYH7 Gly1057Asp as a variant of "uncertain significance". |
