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]

Jan 10, 2022

Center for Genomics, Ann and Robert H. Lurie Children's Hospital of Chicago

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This variant has not been reported in the literature but is present in 0.072% (23/31888) of Latino alleles in the Genome Aggregation Database (http://gnomad.broadinstitute.org/variant/8-47779022-G-A). This variant amino acid Alanine (Ala) is weakly conserved among evolutionarily distant species; this suggests that this variant may not impact the protein. Additional computational prediction tools do not suggest an impact. In summary, data on this variant is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces alanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 3854 of the PRKDC protein (p.Ala3854Val). This variant is present in population databases (rs779943187, gnomAD 0.07%). This variant has not been reported in the literature in individuals affected with PRKDC-related conditions. ClinVar contains an entry for this variant (Variation ID: 569786). 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. -
