Abstract

Three unrelated individuals with, respectively, lupus erythematosus, polyarteritis, and membranoproliferative glomerulonephritis and totally deficient in the second component of complement are demonstrated to be mutually poorly reactive in mixed lymphocyte culture and homozygous for the mixed lymphocyte reaction determinant (MLR-S or LD) short 7a (7a*). The gene controlling the elaboration of C2 in man is shown to be separate from, and probably to map outside of, the second locus of HL-A and the MLR-S locus. Genetic linkage disequilibrium is strongly suggested between HL-A 10, W18, 7a*, and C2 deficiency.
