This allele from project TCPR0523 was generated at The Centre for Phenogenomics by injecting Cas9 ribnucleoprotein complex with synthetic crRNAs with a spacer sequences of UGCCUCAGCAAGAUUUAAAC targeting the 5' side and GGUUCAAGCUAUGGAUUCUG targeting the 3' side of exon ENSMUSE00000269846 resulting in a 847-bp deletion of Chr17 from 10282533 to 10283379 (GRCm38).
