Genes affected

PRKDC (HGNC:9413): (protein kinase, DNA-activated, catalytic subunit) This gene encodes the catalytic subunit of the DNA-dependent protein kinase (DNA-PK). It functions with the Ku70/Ku80 heterodimer protein in DNA double strand break repair and recombination. The protein encoded is a member of the PI3/PI4-kinase family.[provided by RefSeq, Jul 2010]

This sequence change replaces arginine, which is basic and polar, with glycine, which is neutral and non-polar, at codon 3098 of the PRKDC protein (p.Arg3098Gly). This variant is present in population databases (rs377579402, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with PRKDC-related conditions. ClinVar contains an entry for this variant (Variation ID: 583396). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt PRKDC protein function. 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. -
