Association of the top 20 Alzheimer's disease risk genes with [18F]flortaucipir PET. Alzheimers Dement (Amst). 2022;14(1):e12308.

Here, we report the association of these variants with [18F]flortaucipir standardized uptake value ratio (SUVR). Methods: We analyzed the [18F]flortaucipir scans of 352 cognitively normal (CN), 160 mild cognitive impairment (MCI), and 54 dementia (DEM) participants from Alzheimer's Disease Neuroimaging Initiative (ADNI)2 and 3. We ran step-wise regression with log-transformed [18F]flortaucipir meta-region of interest SUVR as the outcome measure and genetic variants, age, sex, and apolipoprotein E (APOE) ε4 as predictors. The results were visualized using parametric mapping at familywise error cluster-level-corrected P < .05. Results: APOE ε4 showed significant (P < .05) associations with tau deposition across all disease stages. Other significantly associated genes include variants in ABCA7 in CN, CR1 in MCI, BIN1 and CASS4 in MCI and dementia participants. Discussion: We found significant associations to tau deposition for ABCA7, BIN1, CASS4, and CR1, in addition to APOE ε4. These four variants have been previously associated with tau metabolism through model systems.en-USAttribution-NonCommercial-NoDerivatives 4.0 InternationalAlzheimer's diseaseAlzheimer's Disease Neuroimaging InitiativeFlortaucipirImaging geneticsRisk genesArticle
