This allele produced from project TCPR0328 at TCP by injecting Cas9 mRNA and one guide RNA with the spacer sequence CTTGTGAAGCCAGACGCGCT and a single-strand oligonucleotide encoding a point mutation. This allele was repaired by NHEJ resulting in a 8-bp deletion (GCGTCTGG) and 1-bp insertion at Chr4:141595354-141595361_insC (GRCm38). (J:200814)
