Beginning with DNA repair genes, less common genotypes in ERCC1 rs11615 (p = 0.011, OR = 0.288 (CI 95% = 0.110–0.751) in a recessive model) and ERCC2 rs13181 (p = 0.046, OR = 0.375 (0.143–0.982) in a codominant model) were associated with a lower risk of laryngeal cancer (Table 2 and Table S2). Here, ERCC1 is linked to laryngeal carcinoma.
