The results consistently highlighted the roles of these genes in multiple aspects of AD pathogenesis [e.g., the top 2 pathways: senile plaque formation (ACTB, ACTG1, APBB1, CHGA, CLU, ENO2, HSPB1, MT3, NRGN, PRNP, SORL1, SYN1, UBB, RTN3) and memory impairment (ACTB, CLU, IDS, KCNQ2, SMAD2, NRGN, PDE2A, PKM, PRKAR1B, PRNP, PSAP, SORL1, SYN1, UBB, CDK5R1, CPLX2, TPPP, GIT1, CALY, REEP2, SLC17A7, JPH3, SLC12A5)] (Fig 4K and S8 Table). This evidence concerns the gene ACTG1 and Alzheimer disease.
