In the present study, therefore, we systematically analyzed the association of 43 SNPs of ten key NER pathway genes (ERCC1, ERCC2, ERCC3, ERCC4, ERCC5, ERCC6, ERCC8, XPA, XPC, and DDB2) with survival of GC patients to investigate whether NER pathway polymorphisms could serve as potential biomarkers for GC prognosis. The gene discussed is ERCC8; the disease is gastric cancer.
