FOXP3 and inborn error of immunity: High FOXP3 expression-related genes were enriched in several immune-related pathways such as intestinal immune network for IgA production (|NES|=2.300, FDR q value<0.001), primary immunodeficiency pathway (|NES|=2.267, FDR q value<0.001), and cytokine–cytokine receptor interaction (|NES|=2.158, FDR q value<0.001).
