Fig. 1From: DNA methylation in the APOE genomic region is associated with cognitive function in African AmericansMethylation pattern in the APOE region. DNA methylation level (%) is represented by the mean β value multiplied by 100 for each of the 48 CpG sites in the PVRL2-TOMM40-APOE-APOC1 region, adjusted for batch effects and white blood cell proportions (N = 289). Error bars represent the standard deviation of methylation level at each CpG site. CpG sites marked with an asterisk (*) are in promoter regions (within 1.5 kb before the transcription start site of the gene)Back to article page
