Leucine codon 85 and tryptophan codon 317 were targeted for changing to arginine using sgRNAs (targeting CAGACTTGGTTTCTAGATGA and CATTTGATACTCTTCGACTC) and ssODN templates with CRISPR/Cas9 technology. This allele knockout allele, with an unspecified frameshifting genome sequence mutation, results from incorrect repair of the targeted sequence. (J:338312)
