The mRNA expression level of CD79A was higher in LUAD tissues than in the non-tumor tissues in six datasets including GSE31210 (p = 3.4e-07), GSE75037 (p = 1e-05), GSE32683 (p = 0.00043), GSE11969 (p = 0.02), GSE30219 (p = 9.9e-06), and GSE81089 (p = 0.0093) (Supplementary Figure S3A), and it was negatively correlated with tumor stages (rho = −0.207, p = 2.59e-06) (Supplementary Figure S3C). Here, CD79A is linked to neoplasm.
