Outline of Final Research Achievements

Recent advances in next generation sequencing technologies have revealed the landscape of human genetic diversity, which is comprised of millions of rare variants associated with health and disease. One possible approach to address the biological function of rare variants, as well as determining whether they are causal for the human phenotype of interest, is the use of precisely modified knockin mouse models carrying such human rare variants. We developed highly efficient, ultra-rapid, and cost-effective genome editing technologies for knockin mouse production. We generated a series of knockin mice mice carrying rare variants discovered from glaucoma patients. We found the pathogenic mechanism of these rare variant to glaucoma-like abnormalities in mice. Our results provide an useful approach to examining in vivo functional significance of rare variants.
