Within pathways related to dementia development, AluS elements mapping to TSS1500 regions within the Protein Kinase N3 (PKN3; cg14036226) and G Protein Subunit β 5 (GNB5; cg24202638) genes (Fig 5A and 5B) and L1M elements (cg22023664 and cg02849894) within the 5’UTR of G Protein Subunit γ 7 (GNG7) (Fig 5C) were differentially methylated. Here, PKN3 is linked to dementia.
