Detailed analysis showed absolute LYM to be significantly correlated with Bcl-2 and with caspase 9 exclusively in IBD patients with active disease (respectively, r=0.38, p=0.040 and r=0.53, p=0.028) and with p53 exclusively in UC patients (r=0.44, p=0.030). The gene discussed is CASP9; the disease is inflammatory bowel disease.
