Answer

Studies of human leukocyte antigens (HLAs) reveal that HLA-A1, HLA-B8, and HLA-DR3 are more common in persons with SLE than in the general population. The presence of the null complement alleles and congenital deficiencies of complement (especially C4, C2, and other early components) are also associated with an increased risk of SLE.
