In an analysis of our IBD dataset, we observed a significant increase of the overall abundance in taxonomically assigned adh genes in CD patients as compared to controls (normal: MR  =  69.39, CD: MR  =  144.10, UC: MR  =  77.76, normal vs CD: p  =  0.000, normal vs UC: p  =  1) (data not shown). The gene discussed is AVP; the disease is inflammatory bowel disease.
