Invitae RCV001308100 SCV001497536 uncertain significance Myofibrillar myopathy 5; Distal myopathy with posterior leg and anterior hand involvement; Hypertrophic cardiomyopathy 26; Dilated Cardiomyopathy, Dominant 2022-08-09 criteria provided, single submitter clinical testing This variant is not present in population databases (gnomAD no frequency). This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 2204 of the FLNC protein (p.Glu2204Lys). This variant has not been reported in the literature in individuals affected with FLNC-related conditions. 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. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). ClinVar contains an entry for this variant (Variation ID: 1010463).
Ambry Genetics RCV003166755 SCV003859343 uncertain significance Cardiovascular phenotype 2023-01-16 criteria provided, single submitter clinical testing The p.E2204K variant (also known as c.6610G>A), located in coding exon 40 of the FLNC gene, results from a G to A substitution at nucleotide position 6610. The glutamic acid at codon 2204 is replaced by lysine, an amino acid with similar properties. This amino acid position is conserved. 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.
