abstract = {Somatic genome editing in mouse models has increased our
understanding of the in vivo effects of genetic alterations.
However, existing models have a limited ability to create
multiple targeted edits, hindering our understanding of
complex genetic interactions. Here we generate transgenic
mice with Cre-regulated and constitutive expression of
enhanced Acidaminococcus sp. Cas12a (enAsCas12a), which
robustly generates compound genotypes, including diverse
cancers driven by inactivation of trios of tumour suppressor
genes or an oncogenic translocation. We integrate these
modular CRISPR RNA (crRNA) arrays with clonal barcoding to
quantify the size and number of tumours with each array, as
well as the impact of varying the guide number and position
within a four-guide array. Finally, we generate tumours with
inactivation of all combinations of nine tumour suppressor
genes and find that the fitness of triple-knockout genotypes
is largely explainable by one- and two-gene effects. These
Cas12a alleles will enable further rapid creation of disease
models and high-throughput investigation of coincident
genomic alterations in vivo.},
