Epigenetic dysregulation is implicated in the pathogenesis of lupus. We performed a longitudinal analysis to assess changes in DNA methylation in lupus granulocytes over 4 years of follow up and across disease activity levels using 229 patient samples. We demonstrate that DNA methylation profiles in lupus are influenced by ancestry-specific genetic variants and are highly stable over time. DNA methylation levels in two CpG sites correlated significantly with changes in lupus disease activity. Pr...
