Although the primary findings were negative, some top CpG sites appeared in both analyses, including loci on the Cell Adhesion Molecule 1 (CADM1), Tubulin alpha 1b (TUBA1B), and Exocyst complex component 2 (EXOC2) genes, which have previously been linked to AD-related pathways. This evidence concerns the gene TUBA1B and Alzheimer disease.
