The association studies of few of the genes associated with various diseases, namely, solute carrier family 11 member 1, Toll-like receptors 1, with TB; Caspase associated recruitment domain 15, SP110 with JD; CACNA2D1, CD14 with mastitis and interferon gamma, BoLA­-DRB3.2 alleles with TTBDs, etc., are presented. Here, SP110 is linked to tuberculosis.
