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]
PRKDC Gene-Disease associations (from GenCC):
  • severe combined immunodeficiency due to DNA-PKcs deficiency

Collection Method:clinical testing

This sequence change replaces leucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 2133 of the PRKDC protein (p.Leu2133Val). This variant is present in population databases (rs573302015, 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: 576325). 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 not expected to disrupt PRKDC protein function with a negative predictive value of 80%. 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.
