Genes affected

POLK (HGNC:9183): (DNA polymerase kappa) This gene encodes a member of the DNA polymerase type-Y family of proteins. The encoded protein is a specialized DNA polymerase that catalyzes translesion DNA synthesis, which allows DNA replication in the presence of DNA lesions. Human cell lines lacking a functional copy of this gene exhibit impaired genome integrity and enhanced susceptibility to oxidative damage. Mutations in this gene that impair enzyme activity may be associated with prostate cancer in human patients. [provided by RefSeq, Sep 2016]

Collection Method: clinical testing

The c.209A>G (p.Q70R) alteration is located in exon 3 (coding exon 2) of the POLK gene. This alteration results from a A to G substitution at nucleotide position 209, causing the glutamine (Q) at amino acid position 70 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
