Meta-integration of IVW results from both cohorts indicated that nine genetically predicted immunophenotypes remained strongly causally associated with IBD, and that genetically predicted HLA DR on plasmacytoid Dendritic Cell, HLA DR on Dendritic Cells, HLA DR on CD33- HLA DR+ and HLA DR on CD14- CD16- had nominal causal associations with IBD (Figure 2). Here, CD33 is linked to inflammatory bowel disease.
