rs1734791 is one of several SNPs in the methyl CpG binding protein 2 (MECP2) that have been associated with risk for systemic lupus erythromatosis (SLE). The MECP2 gene is located on the X chromosome, which may be instructive since lupus is a predominantly female disease.
An initial survey of 600 Korean patients, followed by 1,000 Caucasian patients, ultimately led to a meta-analysis indicating an odds ratio for the rs1734791(A) risk allele of 1.39 (CI: 1.24–1.57, p = 7.2×10−8).[PMID 18320046
