  • Publication number: 20240093316
    Abstract: Methods and compositions are provided herein for assessing CRISPR/Cas-mediated non-homologous end joining (NHEJ) activity and/or CRISPR/Cas-induced recombination of a target genomic locus with an exogenous donor nucleic acid in vivo and ex vivo. The methods and compositions employ cells and non-human animals comprising a Cas expression cassette such as a genomically integrated Cas expression cassette so that the Cas protein can be constitutively available or available in a tissue-specific or temporal-specific manner. Methods and compositions are also provided for making and using these non-human animals, including use of these non-human animals to assess CRISPR/Cas activity in vivo via adeno-associated virus (AAV)-mediated delivery of guide RNAs to the non-human animals.

  • Patent number: 11730150
    Abstract: Provided are non-human animals comprising a mutation in the Fbn1 gene to model neonatal progeroid syndrome with congenital lipodystrophy (NPSCL). Also provided are methods of making such non-human animal models.
