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

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This sequence change replaces cysteine, which is neutral and slightly polar, with arginine, which is basic and polar, at codon 2584 of the PRKDC protein (p.Cys2584Arg). This variant is present in population databases (rs746648336, gnomAD 0.007%). 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: 475237). 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. -
