Importantly, within these pathways, the associations between some of these additionally found genes, such as HLA-C, HLA-G, PRKCQ, PRKCZ, TAP1, TAP2 (formatted in bold in Table 2) and RA were also verified by either OMIM database or by literature retrieved from the NCBI PubMed module. This evidence concerns the gene HLA-G and rheumatoid arthritis.
