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]

Submissions by phenotype

Severe combined immunodeficiency due to DNA-PKcs deficiency Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingInvitaeMay 17, 2018Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site, but this prediction has not been confirmed by published transcriptional studies. 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. This sequence change affects codon 78 of the PRKDC mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the PRKDC protein. This variant is present in population databases (rs746672297, ExAC 0.02%). This variant has not been reported in the literature in individuals with PRKDC-related disease. -
