Several genes related to immune response have also been found in the common sweeps from Fst and XP-EHH analyses, for instance, the cytokine-related genes: TAFA5, TRIM24, CHID1, MUC6 (from arid climate); VTI1B (from humid climate); infection and inflammation-related genes: AGR2, TK2, CMTM3, SUPT4H1 (arid climate); SETD4, ARG2, VTI1B and STRADB (humid climate). The gene discussed is SETD4; the disease is infection.
