Recent studies have revealed some germline loci significantly contributing to the likelihood of EGFR mutation in lung cancer, e.g. 3q28 (rs7636839, TP63), 5p15.33 (re2736100 and rs2853677, TERT), 6p21 (rs2495239, FOXP4; rs3817963, BTNL2; rs2179920, HLA-DPB1), 6q22.2 (rs9387478, ROS1/DCBLD1) and 17q24.3 (rs7216064, BPTF) in Asians [62–64]. The gene discussed is BTNL2; the disease is lung carcinoma.
