This allele from IMPC was generated at Baylor College of Medicine by injecting CAS9 RNA and 4 guide sequences AATCCGGGTTATCTGACACCAGG, TGTCAGATAACCCGGATTTGGGG, TGTCAGATAACCCGGATTTGTGG, ACAAGGGTCATGTGCTACAGAGG, which resulted in a Exon Deletion. Germline transmission of the exon deletion allele from a founder animal failed. (J:265051)
