- We investigated whether IL1RN alleles separately or in combination with MHC class II variants, contribute to susceptibility to SLE and to analysed if IL1RN alleles are markers of disease severity. We investigated 81 patients from a defined area in southern Sweden diagnosed between 1981-1992 and 10 consecutive Caucasian families with multiple cases of SLE. As control group 189 healthy blood donors was used. PCR amplification of defined gene sequences was used in determining the IL1RN polymorphism as well as the MHC class II variants. The IL-1RA levels were measured by an immunoassay. We found an increased frequency of IL1RN*2 in both the epidemiological cohort and in the multicase families (P < 0.01). Alone IL1RN*2 and MHC class II (DR17,DQ2) separately increased the SLE risk moderately. The occurrence of IL1RN*2 and MHC class II variants DR17 and DQ2 together increased the risk to develop SLE by a sevenfold. The IL-1RA gene polymorphism did not correlate with disease severity or with renal involvement. We found an association between IL1RN*1 and arthritis (P < 0.001). Serum level of IL-1RA did not correspond to any specific IL1RN allele. An increased frequency of IL1RN*2 suggests the presence of a gene, implemented in SLE-susceptibility, in the IL1RN region of chromosome 2. IL1RN*2 and specific variants of MHC class II act in synergy to increase disease susceptibility. IL1RN*1 may be a marker of risk for development of arthritis.
