This allele was produced in project TCPR0357 at The Centre for Phenogenomics by injecting Cas9 mRNA and two guide RNAs with the spacer sequences GCAAGACGCGCCTGGCCAAG and GATCGAGGAGGTGCACGCCG. This resulted in a 58-bp deletion in chromosome 7 from 16743267 to 16743324 (GRCm38). This mutation is predicted to cause a frameshift with amino acid changes after residue 18 and early truncation 47 amino acids later (p.K18Pfs*49). (J:165963)
