Meanwhile, compared to the BTLA rs1982809 GG genotype, the BTLA rs1982809 GA and AA+GA genotypes are also associated with the development of NSCLC (GA: OR = 0.81, 95%CI = 0.67‐0.98, and P = 0.030; AA+GA: OR = 0.83, 95%CI = 0.69‐0.99, and P = 0.042). The gene discussed is BTLA; the disease is non-small cell lung carcinoma.
