This allele from project TCPR1593 was generated at The Centre for Phenogenomics by electroporating Cas9 ribonucleoprotein complexes with single guide RNAs having spacer sequences of GCTATCATGTCTCCTACCGA targeting the 5' side and TTCCTCATGTGACCTATCTC targeting the 3' side of a critical region. This resulted in a 560-bp deletion, Chr5:129695815-129696374 (GRCm38). (J:265051)
