| Ambry Genetics | RCV003171537 | SCV003859372 | uncertain significance | Cardiovascular phenotype | 2023-02-28 | criteria provided, single submitter | clinical testing | The p.S743F variant (also known as c.2228C>T), located in coding exon 14 of the FLNC gene, results from a C to T substitution at nucleotide position 2228. The serine at codon 743 is replaced by phenylalanine, an amino acid with highly dissimilar properties. This amino acid position is conserved. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
| Invitae | RCV003779507 | SCV004577386 | uncertain significance | Myofibrillar myopathy 5; Distal myopathy with posterior leg and anterior hand involvement; Hypertrophic cardiomyopathy 26; Dilated Cardiomyopathy, Dominant | 2023-08-23 | criteria provided, single submitter | clinical testing | 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. 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. ClinVar contains an entry for this variant (Variation ID: 2450911). This variant has not been reported in the literature in individuals affected with FLNC-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces serine, which is neutral and polar, with phenylalanine, which is neutral and non-polar, at codon 743 of the FLNC protein (p.Ser743Phe). |
