Genes affected
POLB (HGNC:9174): (DNA polymerase beta) The protein encoded by this gene is a DNA polymerase involved in base excision and repair, also called gap-filling DNA synthesis. The encoded protein, acting as a monomer, is normally found in the cytoplasm, but it translocates to the nucleus upon DNA damage. Several transcript variants of this gene exist, but the full-length nature of only one has been described to date. [provided by RefSeq, Sep 2011]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -12 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.0059150755).
BS1
Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.0105 (1600/152136) while in subpopulation NFE AF= 0.0182 (1234/67988). AF 95% confidence interval is 0.0173. There are 12 homozygotes in gnomad4. There are 723 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
BS2
High Homozygotes in GnomAd4 at 12 AR gene
