Differentially methylated sites associated with Alzheimer’s disease in the anterior hippocampus. DNA methylation profiles of anterior hippocampus samples of 10 non-twin subjects, including six references and four with Alzheimer’s disease (AD), were examined with reduced representation bisulfite sequencing. The samples were from NIH NeuroBioBank. a Differentially methylated sites (201 CpGs) were identified with MethylKit package in R by using a minimum of 15% methylation difference and q value below 0.05 as filtering cutoff (Additional file 2d). The 201 differentially methylated CpG sites overlapped or were closest to 176 genes (AD-associated genes in the brain). Examples of the genes are shown. b Overlap of genes with AD-associated DNA methylation marks in both peripheral blood and anterior hippocampus of the brain
