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]

Collection Method:clinical testing

Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "deleterious"; PolyPhen-2: "benign"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with PRKDC-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change replaces threonine with isoleucine at codon 1424 of the PRKDC protein (p.Thr1424Ile). The threonine residue is highly conserved and there is a moderate physicochemical difference between threonine and isoleucine. 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.
