| Invitae | RCV000687415 | SCV000814979 | uncertain significance | Myofibrillar myopathy 5; Distal myopathy with posterior leg and anterior hand involvement; Hypertrophic cardiomyopathy 26; Dilated Cardiomyopathy, Dominant | 2023-11-20 | criteria provided, single submitter | clinical testing | This sequence change replaces glycine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 2674 of the FLNC protein (p.Gly2674Ser). This variant is present in population databases (rs372338218, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with FLNC-related conditions. ClinVar contains an entry for this variant (Variation ID: 567357). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt FLNC protein function with a negative predictive value of 80%. 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 | RCV002422476 | SCV002679833 | uncertain significance | Cardiovascular phenotype | 2021-01-04 | criteria provided, single submitter | clinical testing | The p.G2674S variant (also known as c.8020G>A), located in coding exon 48 of the FLNC gene, results from a G to A substitution at nucleotide position 8020. The glycine at codon 2674 is replaced by serine, an amino acid with similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
