Genes affected

XRCC1 (HGNC:12828): (X-ray repair cross complementing 1) The protein encoded by this gene is involved in the efficient repair of DNA single-strand breaks formed by exposure to ionizing radiation and alkylating agents. This protein interacts with DNA ligase III, polymerase beta and poly (ADP-ribose) polymerase to participate in the base excision repair pathway. It may play a role in DNA processing during meiogenesis and recombination in germ cells. A rare microsatellite polymorphism in this gene is associated with cancer in patients of varying radiosensitivity. [provided by RefSeq, Jul 2008]

The c.1729A>C (p.M577L) alteration is located in exon 16 (coding exon 16) of the XRCC1 gene. This alteration results from a A to C substitution at nucleotide position 1729, causing the methionine (M) at amino acid position 577 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
