RCV001988730 | SCV002285781 | uncertain significance | Long QT syndrome | 2023-11-20 | criteria provided, single submitter | clinical testing | This sequence change replaces glutamine, which is neutral and polar, with glutamic acid, which is acidic and polar, at codon 202 of the AKAP9 protein (p.Gln202Glu). This variant is present in population databases (rs147876926, gnomAD 0.006%). This variant has not been reported in the literature in individuals affected with AKAP9-related conditions. ClinVar contains an entry for this variant (Variation ID: 1491561). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. 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 | RCV002352709 | SCV002658421 | uncertain significance | Cardiovascular phenotype | 2022-12-18 | criteria provided, single submitter | clinical testing | The p.Q202E variant (also known as c.604C>G), located in coding exon 6 of the AKAP9 gene, results from a C to G substitution at nucleotide position 604. The glutamine at codon 202 is replaced by glutamic acid, an amino acid with highly similar properties. This amino acid position is well conserved in available vertebrate species. 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. |
