However, there were only three (0.6%) proteins with relatively high fold difference (log2 fold difference > 0.25) which were higher in AVS left ventricle compared to CAD left ventricle, which were: sodium channel protein type 5 subunit alpha, 2-oxoisovalerate dehydrogenase subunit alpha and glycogen synthase (Additional file 1: Table S1). This evidence concerns the gene SCN5A and coronary artery disorder.
