Abstract
Non-human animal genomes, non-human animal cells, and non-human animals comprising a humanized TTR locus and methods of using such non-human animal genomes, non-human animal cells, and non-human animals are provided. Non-human animal cells or non-human animals comprising a humanized TTR locus express a human transthyretin protein or a chimeric transthyretin protein, fragments of which are from human transthyretin. Methods are provided for using such non-human animals comprising a humanized TTR locus to assess in vivo efficacy of human-TTR-targeting reagents such as nuclease agents designed to target human TTR. Methods are also provided for making such non-human animals comprising a humanized TTR locus.
