This allele produced from project TCPR0260 at The Centre for Phenogenomics by injecting Cas9 mRNA and one guide RNA with the spacer sequence CAGGGTCTCCGCGCTTTTCG. This resulted in an indel comprised of an 11-bp deletion of Chr2 from 118926684 to 118926694 bp and a 1-bp insertion of A on the +1 strand (GRCm38).
