To investigate the role of module 262 and MEF2A in classification of Crohn's disease, we projected the expression values in the Crohn's dataset to generate an expression value of the module (see Materials and Methods) and found an overall higher expression of the module in patients with Crohn's disease (Fig. 4A, P = 4.6e-09, Wilcoxon rank-sum test). Here, MEF2A is linked to Crohn disease.
