RCV002548570 | SCV001561812 | uncertain significance | Catecholaminergic polymorphic ventricular tachycardia 1 | 2022-03-11 | criteria provided, single submitter | clinical testing | The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 652 of the TRDN protein (p.Glu652Lys). This variant has not been reported in the literature in individuals affected with TRDN-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 disrupt the consensus splice site. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. ClinVar contains an entry for this variant (Variation ID: 1056673). |
Ambry Genetics | RCV002420805 | SCV002722051 | uncertain significance | Cardiovascular phenotype | 2022-04-01 | criteria provided, single submitter | clinical testing | The p.E652K variant (also known as c.1954G>A), located in coding exon 38 of the TRDN gene, results from a G to A substitution at nucleotide position 1954. The glutamic acid at codon 652 is replaced by lysine, an amino acid with similar 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. |
