This allele from project TCPR1410 was generated at The Centre for Phenogenomics by electroporating Cas9 ribonucleoprotein complexes with single guide RNAs having spacer sequences of GAATATAAGACTGACCTCAT targeting the 5' side and TCATTCTGCTTAATTTAGTA targeting the 3' side of a critical region. This resulted in a 526-bp del Chr3:88304784-88305309 (GRCm38). (J:265051)
