As has been shown, rs1127317 located in the ADAR 3′UTR is significantly associated with the survival rate of non-small cell lung cancer (NSCLC) patients and drug response, namely, an elevated ADAR expression and profoundly shortened survival after EGFR-TKI therapy was observed in the carriers of the rs1127317 C allele [33]. The gene discussed is EGFR; the disease is non-small cell lung carcinoma.
