This allele produced from project TCPR0260 at TCP by injecting Cas9 mRNA and one guide RNA with the spacer sequence CAGGGTCTCCGCGCTTTTCG. It was targeted by CRISPR/Cas9 endonuclease-mediated double-strand breaks repaired by NHEJ resulting in a 10-bp deletion Chr2:118926684-118926693 (GRCm38). (J:200814)
