The GTEx database (https://gtexportal.org/home/) predicted that normal lung tissues have a differential expression of the IL-6 rs1800795 variant (p = 7.1 × 10–39) (Fig. S1). Using the GEPIA database (http://gepia.cancer-pku.cn/), the IL-6 gene expression was found to be considerably lower in both AC and SCC tissues comparable with para-tumor tissues (p < 0.01) (Fig. S2A and S2B). The gene discussed is IL6; the disease is neoplasm.
