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]

ACMG classification

Our verdict: Uncertain_significance. The variant received 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 5-75590425-G-A is Pathogenic according to our data. Variant chr5-75590425-G-A is described in ClinVar as Pathogenic. ClinVar VariationId is 218220.Status of the report is criteria_provided_single_submitter, 1 stars.
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.5). . Strength limited to SUPPORTING due to the PP5.
• BP7: Synonymous conserved (PhyloP=1.17 with no splicing effect.
