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]

Jan 03, 2024

The c.598T>G (p.F200V) alteration is located in exon 10 (coding exon 10) of the POLB gene. This alteration results from a T to G substitution at nucleotide position 598, causing the phenylalanine (F) at amino acid position 200 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
