Labcorp Genetics (formerly Invitae), Labcorp RCV001221911 SCV001393982 uncertain significance Myofibrillar myopathy 6; Dilated cardiomyopathy 1HH 2024-06-01 criteria provided, single submitter clinical testing This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 239 of the BAG3 protein (p.Glu239Lys). This variant is present in population databases (rs148544471, gnomAD 0.01%). This missense change has been observed in individual(s) with dilated cardiomyopathy (Invitae). ClinVar contains an entry for this variant (Variation ID: 950240). 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 BAG3 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.
GeneDx RCV001545820 SCV001765224 uncertain significance not provided 2019-09-10 criteria provided, single submitter clinical testing Has not been previously published as pathogenic or benign to our knowledge; Not observed at a significant frequency in large population cohorts (Lek et al., 2016); In silico analysis, which includes protein predictors and evolutionary conservation, supports that this variant does not alter protein structure/function
Ambry Genetics RCV003163708 SCV003864728 uncertain significance Cardiovascular phenotype 2022-11-27 criteria provided, single submitter clinical testing The p.E239K variant (also known as c.715G>A), located in coding exon 3 of the BAG3 gene, results from a G to A substitution at nucleotide position 715. The glutamic acid at codon 239 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.
