| Invitae | RCV001299769 | SCV001488879 | uncertain significance | Myofibrillar myopathy 5; Distal myopathy with posterior leg and anterior hand involvement; Hypertrophic cardiomyopathy 26; Dilated Cardiomyopathy, Dominant | 2024-01-17 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 1027 of the FLNC protein (p.Arg1027Cys). This variant is present in population databases (rs541775814, gnomAD 0.0009%). This missense change has been observed in individual(s) with hypertrophic cardiomyopathy (PMID: 30411535). ClinVar contains an entry for this variant (Variation ID: 1003240). 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on FLNC 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 | RCV002319696 | SCV002608653 | uncertain significance | Cardiovascular phenotype | 2022-04-11 | criteria provided, single submitter | clinical testing | The p.R1027C variant (also known as c.3079C>T), located in coding exon 20 of the FLNC gene, results from a C to T substitution at nucleotide position 3079. The arginine at codon 1027 is replaced by cysteine, an amino acid with highly dissimilar properties. This variant has been detected in an individual from a hypertrophic cardiomyopathy cohort; however, details were limited and another variant may have also been detected (Cui H et al. Mol Genet Genomic Med, 2018 11;6:1104-1113).This amino acid position is not well conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
