Next, a few genes were verified by qPCR experiments with the samples from our hospital; FPR2, ITGAM, C3AR1, FCER1G, CYBB in DEG-MEgreen, and GNG4, NMUR2 and GNG7 in DEG-MEturquoise were confirmed to be related to the pathogenesis and phenotype of CRSwNP. Here, ITGAM is linked to chronic rhinosinusitis with nasal polyps.
