Although somewhat lacking in statistical power, several reports have linked rs1800947, a synonymous mutation known as CRP2 in the C-reactive protein CRP to the autoimmune disorder SLE, systemic lupus erythematosus. The risk allele in dbSNP orientation is (C). [PMID 14645206, PMID 15897982, PMID 18216863]
