Generation of an AMS zebrafish model using the zAncBE4max system. a The designed target site in the twist2 gene on chromosome 9 in zebrafish. The nucleotide changes in C-to-T editing are underlined in red. The corresponding amino acid change is E78K. PAM region is indicated in blue. b Homozygous mutant (E78K) embryos exhibit a short truck and curved tail (red arrowheads) at 48 hpf. Scale bar, 100 μm. c Genotyping of homozygous mutant larva by PCR and sequencing. Red arrow indicates point mutation site C-to-T. d Phenotype of heterozygous mutants (E78K) exhibited a protruding jaw, unclosed mouth (red arrows), and emaciated body at the age of 6 months. For more details, see Additional file 3: Movie 1. e qRT-PCR analysis indicates the relative expression levels of twist2 and related genes in twist2 homozygous E78K mutant embryos
