FAS and type 1 diabetes mellitus: Within the identified co-expression disease modules that were chosen for further analysis, we found several significantly enriched Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways with association to T1D, such as Type I diabetes mellitus, mTOR signaling pathway etc. Besides confirming some genes with previously known T1D involvement, such as fas cell surface death receptor (FAS), interleukin 1 beta (IL1B) and interleukin 8 (IL8), we also identified interesting candidate genes that could be further analyzed further to understand their roles in T1D.
