Non‐inherited maternal HLA alleles are associated with rheumatoid arthritis
Background. Rheumatoid arthritis (RA) is strongly associated with a series of HLA‐DRB1 alleles that encode a conserved sequence of amino acids (70Q/R K/R R A A74) in the DRβ1 chain, known as the shared epitope (SE). However 30% of patients are negative for DRB1*04 and 15% are SE‐negative. Exposure t...

Background. Rheumatoid arthritis (RA) is strongly associated with a series of HLA‐DRB1 alleles that encode a conserved sequence of amino acids (70Q/R K/R R A A74) in the DRβ1 chain, known as the shared epitope (SE). However 30% of patients are negative for DRB1*04 and 15% are SE‐negative. Exposure to these alleles as non‐inherited maternal antigens (NIMA) might explain this discrepancy. We undertook a family study to investigate the role of NIMA in RA. Methods. One hundred families, including the RA proband and both parents, were recruited. HLA‐DRB1 genotyping was performed using an allele‐specific polymerase chain reaction by standard methods. The frequencies of NIMA and non‐inherited paternal antigens (NIPA) were compared using contingency tables and a two‐tailed P test. We then reviewed four previously published studies of NIMA in RA and conducted an analysis of the combined data Results. We identified 36 families in which the proband was DRB1*04‐negative and 13 in which the proband lacked the SE. There was an excess of DRB1*04 and SE NIMA (P=0.05) compared with NIPA. Combined analysis with previous studies showed that 53/231 mothers (23%) versus 25/205 fathers (12%) had a non‐inherited DRB1*04 (P=0.003) and 30/99 mothers versus 18/101 fathers had a non‐inherited SE allele (P=0.03). Conclusion. A role for HLA NIMA in RA is suggested by these results. |
