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

The c.1003A>G (p.K335E) alteration is located in exon 11 (coding exon 11) of the PRKDC gene. This alteration results from a A to G substitution at nucleotide position 1003, causing the lysine (K) at amino acid position 335 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
