Figure 1From: Analysis of HLA DR, HLA DQ, C4A, FcγRIIa, FcγRIIIa, MBL, and IL-1Ra allelic variants in Caucasian systemic lupus erythematosus patients suggests an effect of the combined FcγRIIa R/R and IL-1Ra 2/2 genotypes on disease susceptibilityDistribution of genetic variants studied in 143 patients with SLE and 200 healthy blood donors. DR3 represents the haplotype DR3-DQ2-C4AQ0. F, phenylalanine; H, histidine; Int, intermediate; MBL, mannan-binding lectin; R, arginine; V, valine.Back to article page
