Nucleotide excision repair (NER) is instrumental in removing DNA lesions caused by ultraviolet (UV) radiation, the dominant risk factor for keratinocyte carcinoma, including basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). We evaluated whether BCC or SCC risk was influenced by the A23G single nucleotide polymorphism (SNP) in Xeroderma(More)
BACKGROUND Arsenic exposure may alter the efficiency of DNA repair. UV damage is specifically repaired by nucleotide excision repair (NER), and common genetic variants in NER may increase risk for non-melanoma skin cancer (NMSC). OBJECTIVE We tested whether polymorphisms in the NER genes XPA (A23G) and XPD (Asp312Asn and Lys751Gln) modify the association(More)
