Since several of the genes that build the densely connected cluster in the Royalblue module are related to the immune diseases, it is of great interest to further investigate other genes in that cluster (i.e. ATXN7, PGGT1B, MIS18BP1) that have not been previously associated with T1D, and may contribute to extending our knowledge about the disease. This evidence concerns the gene ATXN7 and type 1 diabetes mellitus.
