RCV000038840 | SCV000062518 | uncertain significance | not specified | 2012-02-07 | criteria provided, single submitter | clinical testing | The Arg285His variant (VCL) has not been reported in the literature, but has bee n identified in one proband with HCM (this individual's son) by our laboratory. Arginine (Arg) at position 285 is not completely conserved across different spec ies, increasing the likelihood that a change would be tolerated. Computational a nalyses (biochemical amino acid properties, AlignGVGD, PolyPhen2, and SIFT) also suggest that the Arg285His variant may not impact the protein, though this info rmation is not predictive enough to rule out pathogenicity. Variants in the VCL gene have been found in individuals with HCM as well as DCM (Olson 2002, Vasile 2006). However, the number of studies is still small and the contribution of VCL to HCM and DCM, as well as the types of variants that cause disease, have not b een well established. Additional information is needed to fully assess the clini cal significance of this variant. |
Invitae | RCV001059935 | SCV001224590 | uncertain significance | Dilated cardiomyopathy 1W | 2022-08-04 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 285 of the VCL protein (p.Arg285His). This variant is present in population databases (rs397517246, gnomAD 0.003%). This variant has not been reported in the literature in individuals affected with VCL-related conditions. ClinVar contains an entry for this variant (Variation ID: 45621). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Not Available". The histidine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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 | RCV004678599 | SCV005179528 | likely benign | Cardiovascular phenotype | 2024-04-26 | criteria provided, single submitter | clinical testing | This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. |
