Similar analysis of three independent RA cohorts from British, Dutch and Norwegian populations also indicated an absence of significant interaction between genetic variants in CIITA and SE alleles with regard to RA risk.Our data suggest that risk from the CIITA locus is independent of the major risk for RA from HLA-DRB1 SE alleles, given that no significant interaction between rs3087456 and SE alleles was observed.
A promoter SNP -168A→G (rs3087456) has previously been shown to be associated with susceptibility to several immune mediated disorders, including rheumatoid arthritis (RA), multiple sclerosis (MS) and myocardial infarction (MI).
Our results indicate that the MHC2TA -168A/G polymorphism (rs3087456) is not associated with RA yet underscore the importance of including shared epitope allele carrier status, secondary phenotypes and more complete characterisation of MHC2TA variation in future studies.
A promoter polymorphism (-168A/G, rs3087456) in the MHC2TA gene was associated with increased susceptibility to rheumatoid arthritis, multiple sclerosis and myocardial infarction in a northern European population.
MHC2TA promoter polymorphism (-168*G/A, rs3087456) is not associated with susceptibility to rheumatoid arthritis in British Caucasian rheumatoid arthritis patients.
We analysed whether the single nucleotide polymorphism (SNP) rs3087456 in the promoter of the MHC class II transactivator (MHC2TA) gene is associated with manifestation of rheumatoid arthritis, multiple sclerosis, narcolepsy and Wegener granulomatosis.

We also confirm interaction between rs4774 and HLA-DRB1*15:01 such that individuals carrying the risk allele for rs4774 and HLA-DRB1*15:01 have a higher than expected risk for MS.
A CIITA promoter single-nucleotide polymorphism (SNP), rs3087456 (-168 A/G), has indeed been associated with several autoimmune diseases, including rheumatoid arthritis (RA).
