Thus, these results appear to be concordant with the best functional candidate genes found in each QTL region, with the ABCC4 (BTA12) and IERC (BTA23) genes appearing to be directly involved in responses to infection, whereas the CBFA2T2 gene (BTA13) was previously found to be associated with intestinal inflammation or abnormal morphology in mice. This evidence concerns the gene CBFA2T2 and infection.
