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]
[PMID 19333917] Variants within MECP2, a key transcription regulator, are associated with increased susceptibility to lupus and differential gene expression in patients with systemic lupus erythematosus.
[PMID 19717458] A common MECP2 haplotype associates with reduced cortical surface area in humans in two independent populations.
