JO - Alzheimer's research & therapy VL - 15 IS - 1 SN - 1758-9193 CY - London PB - BioMed Central M1 - DKFZ-2023-01532 SP - 129 PY - 2023 N1 - #EA:C070#LA:C070# AB - In order to utilize polygenic risk scores (PRSs) for Alzheimer's disease (AD) in a meaningful way, influential factors (i.e. training set) and prediction across groups such as APOE e4 (APOE4) genotype as well as associations to dementia-related biomarkers should be explored. Therefore, we examined the association of APOE4 and various PRSs, based on training sets that utilized differing AD definitions, with incident AD and all-cause dementia (ACD) within 17 years, and with levels of phosphorylated tau181 (P-tau181), neurofilament light (NfL), and glial fibrillary acidic protein (GFAP) in blood. Secondarily, effect modification by APOE4 status and sex was examined.In this prospective, population-based cohort study and nested case-control study, 9,940 participants in Germany were enrolled between 2000 and 2002 by their general practitioners and followed for up to 17 years. Participants were included in this study if dementia status and genetic data were available. A subsample of participants additionally had measurements of P-tau181, NfL, and GFAP obtained from blood samples. Cox and logistic regression analyses were used to assess the association of genetic risk (APOE genotype and PRSnoAPOE) with incident ACD/AD and log-transformed blood levels of P-tau181, NfL, and GFAP.Five thousand seven hundred sixty-five participants (54 KW - Alzheimer’s disease (Other) KW - Blood-biomarkers (Other) KW - Polygenic risk scores (Other) LB - PUB:(DE-HGF)16 C6 - pmid:37516890 C2 - pmc:PMC10386275 DO - DOI:10.1186/s13195-023-01277-8 UR - https://inrepo02.dkfz.de/record/277864 ER -
