The NM_006904.7(PRKDC):c.10211G>A (p.Gly3404Glu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The gene PRKDC is a tumor suppressor gene (CancerMine: 3 TSG, 11 oncogene, 7 driver citations). The gene PRKDC is a known oncogene (CancerMine: 3 TSG, 11 oncogene, 7 driver citations). The gene PRKDC is a cancer driver gene (CancerMine: 3 TSG, 11 oncogene, 7 driver citations). The variant allele was found at a cumulative frequency of 0.0146 (AC=23,615) in the gnomAD database across 1,613,624 control chromosomes, including 230 homozygotes. The grpmax filtering allele frequency (95% CI) is 0.0189. In-silico predictor (REVEL) classifies this variant as likely benign. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. Variant has been reported in ClinVar as Benign/Likely Benign (★★). The variant has been observed in cBioPortal in 4 samples across 2 studies and 2 cancer types; somatic enrichment level: SUPPORTING_LOW (Observed in a small number of cBioPortal cases.). This exact variant is curated in the UniProt human variants database as Uncertain Significance; it is also listed as a COSMIC curated somatic variant.

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
