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

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

The p.S1409F variant (also known as c.4226C>T), located in coding exon 33 of the PRKDC gene, results from a C to T substitution at nucleotide position 4226. The serine at codon 1409 is replaced by phenylalanine, an amino acid with highly dissimilar properties. This amino acid position is conserved. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -

Severe combined immunodeficiency due to DNA-PKcs deficiency Uncertain:1
Jun 27, 2022
Labcorp Genetics (formerly Invitae), Labcorp
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This sequence change replaces serine, which is neutral and polar, with phenylalanine, which is neutral and non-polar, at codon 1409 of the PRKDC protein (p.Ser1409Phe). This variant is present in population databases (rs376814572, gnomAD 0.08%). 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: 565334). 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. -
