This included chromosome 15 (29 Mb; ARRB1, RELT and ATG16L2), 20 (9 Mb; MAP1B), 2 (102 Mb; KCNH7), 17 (25 Mb, ULK1), 3 (54 Mb; IFI44L and IFI44), 18 (7 Mb; DOK4 and MAF), 5 (75 Mb; IL2RB) and 26 (34 Mb; PIK3AP1, DNTT, BLNK) as the most important genomic regions potentially contributing to the incidence of brucellosis in the examined goat population. The gene discussed is IL2RB; the disease is brucellosis.
