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]

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

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. ClinVar contains an entry for this variant (Variation ID: 541991). This variant has not been reported in the literature in individuals affected with PRKDC-related conditions. This variant is present in population databases (rs746489977, gnomAD 0.006%). This sequence change replaces glycine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 1544 of the PRKDC protein (p.Gly1544Ser).
