RCV004788375 | SCV005400201 | uncertain significance | Hypertrophic cardiomyopathy 1 | 2023-07-16 | criteria provided, single submitter | clinical testing | Based on the classification scheme VCGS_Germline_v1.3.4, this variant is classified as VUS-3B. Following criteria are met: 0105 - The mechanism of disease for this gene is not clearly established; however, missense variants have been proposed to act in a dominant negative manner (PMID: 24714796). (I) 0108 - This gene is associated with both recessive and dominant disease. Pathogenic variants in this gene are usually heterozygous; however, a recessive inheritance pattern has been observed in severe cases (OMIM). (I) 0112 - The condition associated with this gene has incomplete penetrance (PMID: 29300372). (I) 0200 - Variant is predicted to result in a missense amino acid change from glycine to valine. (I) 0251 - This variant is heterozygous. (I) 0301 - Variant is absent from gnomAD (both v2 and v3). (SP) 0309 - An alternative amino acid change at the same position has been observed in gnomAD (v2 and v3) (p.(Gly1520Arg): 5 heterozygotes, 0 homozygotes). (I) 0501 - Missense variant consistently predicted to be damaging by multiple in silico tools or highly conserved with a major amino acid change. (SP) 0600 - Variant is located in the annotated myosin tail 1 domain (DECIPHER). (I) 0710 - Another missense variant comparable to the one identified in this case has inconclusive previous evidence for pathogenicity. The p.(Gly1520Arg) variant has been classified as a VUS by Invitae (Clinvar). It has also been reported in one individual with sporadic dilated cardiomyopathy (DCM) and proposed by the authors as a having potential risk of sporadic DCM (PMID: 35284542). (I) 0809 - Previous evidence of pathogenicity for this variant is inconclusive. This variant has been observed in one individual with hypertrophic cardiomyopathy; however, the classification of the variant is unclear (PMID: 31941943). (I) 0905 - No published segregation evidence has been identified for this variant. (I) 1007 - No published functional evidence has been identified for this variant. (I) 1208 - Inheritance information for this variant is not currently available in this individual. (I) Legend: (SP) - Supporting pathogenic, (I) - Information, (SB) - Supporting benign |
