Lupus, more technically known as systemic lupus erythematosus and often abbreviated as SLE, is a complex autoimmune disease. The most studied genetic contributions to SLE involve the major histocompatibility complex (MHC) region on chromosome 6, which contains over 100 genes involved in immune system function.

In the MHC, one allele in the class II region, and one SNP in the class III region, have been associated with risk for developing lupus [PMID 17997607]:

  • The HLA-DRB1*0301 allele from the class II region - see rs2187668; and,
  • rs419788, a SNP in the intron of the class III SKIV2L gene


SNPs outside of the MHC region that have been reported to affect the risk of developing lupus include:

  • A region on chromosome 8p23.1, upstream of the BLK gene:
