Our results suggested that Arg399Gln variant of <i>XRCC1</i> gene might be a risk factor for NMSC in Asian populations, and Arg194Trp variant of <i>XRCC1</i> gene might be a protective factor for patients with SCC.
Our data suggest that the Arg194Trp polymorphism could be associated with nonmelanoma skin cancer and extramammary Paget's disease risk in a Japanese population.
