Methylation profile of individuals with sickle cell trait.

ABSTRACT: Sickle cell trait (SCT) is due to heterozygosity for the β-globin sickle cell mutation. SCT recently has been associated with increased risk of various adverse health outcomes. DNA methylation (DNAm) is one potential mechanism by which SCT may impact disease risk. To identify DNAm sites associated with SCT, we conducted an epigenome-wide association (EWAS) meta-analysis using whole blood Illumina EPIC array data available in a total of 3,677 African American participants (including 1,071 with SCT) from the Women's Health Initiative and Jackson Heart Study. We identified 103 differentially methylated CpGs and 119 differentially methylated regions associated with SCT. The strongest signals were hypermethylated cis loci within predicted regulatory elements within or near the β-globin gene clu
