Abstract excerpt
X-ray repair cross-complementing 1 (XRCC1) gene encodes for a scaffolding protein, which plays an important role in base excision DNA repair by bringing together DNA polymerase beta, DNA ligase III and poly(ADP-Ribose) polymerase (PARP) at the site of DNA damage. Three polymorphisms of the XRCC1 gene at codons 194, 280 and 399 leading to amino acid changes at evolutionary conserved regions are found to alter the...
