In genotype model, subjects with RAD54L2 rs9864693 GC heterozygote genotype might have an increased risk of lung cancer compared with individuals with GG wild-type genotype (crude analysis: OR = 1.33, 95%CI: 1.01–1.76, p = 0.046; adjusted analysis: OR = 1.33, 95%CI: 1.01–1.77, p = 0.045) (Table 3). Here, RAD54L2 is linked to lung cancer.
