Once again, SNP rs2285521 showed a significant correlation with decreased mRNA expression levels of GGA2 in lung cancer tissues, specifically in both additive (P = 4.85 × 10−3, Fig. 3i) and recessive (P = 8.29 × 10−3, Fig. 3j) models for LUSC, but not for LUAD (Supplementary Fig. 2e, f). This evidence concerns the gene GGA2 and lung cancer.
