This is a good work. Key word is variants, such as SNPs.
Very large samples: 6,609 never-smoking Asian female lung cancer cases and 7,457 controls
new susceptibility loci found:
10q25.2
6q22.2 and 6p21.32 (ROS1 gene)
previously identified loci confirmed:
5p15.33
3q28
17q24.3
A point to make here - the two most known gene alterations that cause as much as 35% of lung adenocarcinoma in Asian women, EGFR and ALK, are located on chromosome 7 and 2 respectively. It is reasonable to draw side conclusion from such large study, that EGFR mutation or amplification, as well as xxxx-ALK fusion, as root causes of nonsmoker lung cancer, are not inherited susceptibility. On the other hand, the cause of CD74-ROS1 driven lung cancer might have significant family genetic contribution. A friend who's cancer is ROS1 positive just suggested that his family be tested for susceptibility, after learning of this recent study.
RET oncogene is on 10q11.2, K-ras on 12, MET and BRAF on 7, so it is not likely the other 4 loci situated a known lung cancer oncogene.
