Description

The PKD2 c.170A>G variant is predicted to result in the amino acid substitution p.Gln57Arg. To our knowledge, this variant has not been reported in the literature or in a large population database, indicating this variant is rare; however the quality of this data is questionable and should be interpreted with caution. The codon is a weakly conserved amino acid. Additionally, at PreventionGenetics, this variant was reported in an individual undergoing testing for autosomal dominant polycystic kidney disease, who also harbored a pathogenic nonsense variant in the PKD1 gene (internal data). Although we suspect this variant may be benign, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence.
