Furthermore, despite absence of statistical interactions, effects of diabetes were significant at E9.5 for expression levels of Cpt1a (27.8%), Slc27a6/Fatp6 (10.8%), Slc2a13/Glut13 (7.2%), Cpt1c (6.4%), Slc2a6/Glut6 (3.2%) and Cpt2 (1.95%), but diet influence was much stronger for these genes with 48.5%, 51.4%, 83.8%, 80.4%, 84.2%, and 94.1% of variation attributable to diet, respectively). The gene discussed is SLC27A6; the disease is diabetes mellitus.
