Invitae RCV001212353 SCV001383936 uncertain significance Developmental and epileptic encephalopathy, 12 2022-05-29 criteria provided, single submitter clinical testing This variant has not been reported in the literature in individuals affected with PNKP-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 missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The serine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. ClinVar contains an entry for this variant (Variation ID: 942373). This variant is not present in population databases (gnomAD no frequency). This sequence change replaces alanine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 428 of the PNKP protein (p.Ala428Ser).
