Therefore, using CHi-C and validated by 3C-qPCR, we have confirmed that an intergenic region containing SNPs associated with RA, T1D, SLE, CeD and IBD, tagged by rs6920220 interacts with IL20RA, IFNGR1 and the lncRNAs RP11-10J5.1 and RP11-240M16.1. Here, IL20RA is linked to cranioectodermal dysplasia.
