This allele from project TCPR1137 was generated at The Centre for Phenogenomics by electroporating Cas9 ribonucleoprotein complexes with single guide RNAs having spacer sequences of GCTCCGCGAGTTGTTGGCGG, AAAAGACGTCCAGCGGCGAG and GGGTCCACGAGGTGGTGTAG targeting a critical exon. This resulted in a 36-bp deletion Chr19:46003690 to 46003725 and 2,084-bp del Chr19:46003853 to 46005936 (GRCm38). (J:265051)
