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

Classification was made for transcript

Our verdict: Benign. The variant received -11 ACMG points.

PP2
Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 14 curated pathogenic missense variants (we use a threshold of 10). The gene has 0 curated benign missense variants. Gene score misZ: 0.28752 (below the threshold of 3.09). Trascript score misZ: 0.94642 (below the threshold of 3.09).
BP4
Computational evidence support a benign effect (MetaRNN=0.002148807).
BS1
Variant frequency is greater than expected in population eas. GnomAd4 allele frequency = 0.00208 (317/152344) while in subpopulation EAS AF = 0.0274 (142/5186). AF 95% confidence interval is 0.0237. There are 1 homozygotes in GnomAd4. There are 148 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
BS2
High Homozygotes in GnomAdExome4 at 9 AR gene
