This allele from project Cdk19-5832J-2074 was generated at The Jackson Laboratory by injecting Cas9 RNA and 18mer guide sequence GTGGGACGCGGCACCTAC, which resulted in an 11 bp deletion CGGCACCTACG in exon1 beginning at Chromosome 10 positive strand position 40,349,680 bp (GRCm38). This mutation is predicted to cause amino acid sequence changes after residue 29 and early truncation 12 amino acids later.
