Invitae RCV000464373 SCV000546199 uncertain significance Hypertrophic cardiomyopathy 2018-05-14 criteria provided, single submitter clinical testing This sequence change replaces arginine with histidine at codon 1925 of the MYH7 protein (p.Arg1925His). The arginine residue is highly conserved and there is a small physicochemical difference between arginine and histidine. This variant is present in population databases (rs752553589, ExAC 0.001%) but has not been reported in the literature in individuals with a MYH7-related disease. ClinVar contains an entry for this variant (Variation ID: 407171). A computational algorithm designed to assess the pathogenicity of variants in MYH7 with regard to hypertrophic cardiomyopathy predicted this sequence change to be deleterious. The algorithm has a sensitivity of 94% and a specificity of 89% (PMID: 21310275). In summary, this variant is a rare missense change with uncertain impact on protein function. It is not expected to cause disease, but the available evidence is currently insufficient to prove that conclusively. Therefore, it has been classified as a Variant of Uncertain Significance.
