When compared with AD; beta‐secretase‐1 (BACE1), cystatin C (CST3), GDP‐dissociation inhibitor‐1 (GDI1), insulin‐like GF‐binding protein‐7 (IGFBP7), IL15, pleiotrophin (PTN), and synaptosomal‐associated protein 25 (SNAP25) had lower odds for the FTD group. This evidence concerns the gene IGFBP7 and frontotemporal dementia.
