| Ambry Genetics | RCV002446439 | SCV002734927 | uncertain significance | Familial thoracic aortic aneurysm and aortic dissection | 2018-01-15 | criteria provided, single submitter | clinical testing | The p.A364V variant (also known as c.1091C>T), located in coding exon 10 of the PRKG1 gene, results from a C to T substitution at nucleotide position 1091. The alanine at codon 364 is replaced by valine, an amino acid with similar properties. This amino acid position is not 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. |

RCV003098799 | SCV003280403 | uncertain significance | Aortic aneurysm, familial thoracic 8 | 2025-01-19 | criteria provided, single submitter | clinical testing | This sequence change replaces alanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 364 of the PRKG1 protein (p.Ala364Val). This variant is present in population databases (rs369811301, gnomAD 0.07%). This variant has not been reported in the literature in individuals affected with PRKG1-related conditions. ClinVar contains an entry for this variant (Variation ID: 1789430). 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 tolerated. 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. |
