The GR-AD project aims to create mouse models that precisely recapitulate human Alzheimer's disease and related dementias genetics by completely replacing mouse genes with their full human orthologs. The approach involves generating mouse lines where genes of interest are precisely and completely replaced in the mouse genome by their full human counterparts. Each model set consists of a control line carrying a wild-type human allele and variant lines that precisely match the human genomic sequence in the control line, differing only by high-impact pathogenic mutations or risk variants. This methodology represents a comprehensive approach to modeling the genetic complexity of human AD/ADRD in animal models, moving beyond traditional transgenic approaches to achieve more faithful representation of human disease genetics. The project addresses the field's limited success in incorporating the rich complexity of human AD/ADRD genetic findings into animal models by creating mice that carry actual human gene sequences rather than overexpressed transgenes.
PRIMARY OUTCOME
Generation of mouse lines with complete human gene replacement
EXPECTED OUTCOMES
Mouse models that accurately model human AD/ADRD genetics with each model set containing matched control and variant lines differing only in specific mutations
SUCCESS CRITERIA
Successful generation of mouse lines with precise human gene replacement and functional modeling of human AD/ADRD genetics
PROTOCOL
Precise and complete replacement of mouse genes with full human orthologs in the mouse genome, creating control lines with wild-type human alleles and variant lines with pathogenic mutations or risk variants
