HLA-DRB1 genotypes and the risk of developing anti citrullinated protein antibody (ACPA) positive rheumatoid arthritis.

<h4>Objective</h4>To provide a table indicating the risk for developing anti citrullinated protein antibody (ACPA) positive rheumatoid arthritis (RA) according to one's HLA-DRB1 genotype.<h4>Methods</h4>We HLA-DRB1 genotyped 857 patients with ACPA positive RA and 2178 co...

HLA-DRB1 genotypes with HLA-DRB104SE (HLA-DRB10404, HLA-DRB10405, HLA-DRB10408), HLA-DRB104∶01, HLA-DRB101 are usually associated with high risk for developing RA. The second HLA-DRB1 allele in genotype somewhat modulates shared epitope associated risk. We did not identify any absolutely protective allele. Neither the Reviron, nor the du Montcel models accurately explains our data which are compatible with the shared epitope hypothesis and suggest a dosage effect among shared epitope positive HLA-DRB1 alleles, double dose genotypes carrying higher ORs than single dose genotypes.<h4>Conclusion</h4>HLA-DRB1 genotypic risk for developing ACPA positive RA is influenced by both HLA-DRB1 alleles in genotype.
