This allele was generated at The Jackson Laboratory by electroporating Cas9 protein and 2 guide sequences: GGGGTAGAGGGGACCTGTGA and TTAGAAAATACTGCAGTCCC. This resulted in a 1,598 bp deletion of Chr9:7,386,141-7,387,738 (GRCm38/mm10) that removes exon ENSMUSE00000302943, ENSMUSE00000983617 and ENSMUSE00000302891.
