Gene replacement-Alzheimer's disease (GR-AD): Modeling the genetics of human dementias in mice. Alzheimers Dement. 2024;20(4):3080-3087. doi:10.1002/alz.13730https://hdl.handle.net/1805/42172Introduction: Genetic studies conducted over the past four decades have provided us with a detailed catalog of genes that play critical roles in the etiology of Alzheimer's disease (AD) and related dementias (ADRDs). Despite this progress, as a field we have had only limited success in incorporating this rich complexity of human AD/ADRD genetics findings into our animal models of these diseases. Our primary goal for the gene replacement (GR)-AD project is to develop mouse lines that model the genetics of AD/ADRD as closely as possible. Methods: To do this, we are generating mouse lines in which the genes of interest are precisely and completely replaced in the mouse genome by their full human orthologs. Results: Each model set consists of a control line with a wild-type human allele and variant lines that precisely match the human genomic sequence in the control line except for a high-impact pathogenic mutation or risk variant.en-USAttribution-NonCommercial-NoDerivatives 4.0 InternationalFunctional sequence variantGene‐replacement mouse modelProtective haplotypeRisk haplotypeArticle
