Familial thoracic aortic aneurysm and aortic dissection Uncertain:1
The c.395A>G (p.D132G) alteration is located in exon 2 (coding exon 2) of the PRKG1 gene. This alteration results from a A to G substitution at nucleotide position 395, causing the aspartic acid (D) at amino acid position 132 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
not provided Uncertain:1
A variant of uncertain significance has been identified in the PRKG1 gene. The D132G variant has not been published as pathogenic or been reported as benign to our knowledge. This variant has been observed in 1/10402 (0.010%) alleles from individuals of African ancestry, 1/11404 (0.009%) alleles from individuals of Latino ancestry, and 5/66650 (0.008%) alleles from individuals of Non-Finnish European ancestry, in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). The D132G variant is a non-conservative amino acid substitution, which is likely to impact secondary protein structure as these residues differ in polarity, charge, size and/or other properties. Additionally, this substitution occurs at a position that is conserved across species and in silico analysis predicts this variant is probably damaging to the protein structure/function. Nevertheless, this variant has not been observed in a significant number of affected individuals, and it lacks both segregation and functional studies which would further clarify its pathogenicity. -
Aortic aneurysm, familial thoracic 8 Uncertain:1
This sequence change replaces aspartic acid, which is acidic and polar, with glycine, which is neutral and non-polar, at codon 132 of the PRKG1 protein (p.Asp132Gly). This variant is present in population databases (rs140871298, gnomAD 0.006%). 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: 451745). 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. -
