Cells in the ILC35 cluster differentially expressed genes such as PCDH9, KIT, ALDOC and AHR. Expression analysis of the GWAS-associated genes containing CeD-related SNPs obtained from a publicly available catalog (The NHGRI-EBI Catalog of human genome-wide association studies-EFO_0001060) showed complex patterns occurring in both CeD and GFD cells (Fig. 3e). The gene discussed is PCDH9; the disease is cranioectodermal dysplasia.
