Generation of elovl2 mutant zebrafish with CRISPR/Cas9 genome editing. A: Schematic of the elovl2 gene and gRNA sequences, identified as targets A and B. B: Genomic sequences for wild-type elovl2 and one of the two generated mutant alleles, elovl2co100. Sequence peak tracings and PCR verification are shown in Supplemental Fig. 2. The elovl2co100 allele has a 157 bp deletion (107 bp in exon 3; 50 bp in intron 3) and 13 bp insertion in exon 4. C: Schematic of predicted Elovl2 protein in wild-type (260 AA) and elovl2co100 (80 AA) fish. Genomic and protein results for the second generated mutant allele (elovl2co101) are shown in Supplemental Fig. 1. All experiments were conducted using elovl2co100 mutants unless otherwise noted.
