Consistent with this, the Pearson correlation coefficients between NOD2 and SNX20 mRNA levels are 0.69, 0.54, 0.54 in neutrophils, monocytes and CD4 T cells respectively (PEER-adjusted IBD-HV expression data), and ENCODE data suggests active regulatory elements in this region (Fig 8). This evidence concerns the gene SNX20 and inflammatory bowel disease.
