Genetic variants of interest identified in several immune related genes for all the antibody response and parasitic infection traits: IBDV (TOLLIP, ANGPTL5, BCL9, THEMIS2), MDV (GRM7), SG (MAP3K21), Eimeria (TOM1L1), and cestodes (TNFAIP1, ATG9A, NOS2). Here, TOLLIP is linked to parasitic infectious disease.
