This allele was generated at The Jackson Laboratory by electroporating Cas9 protein and 2 guide sequences GAGACTGAAGTAACCAGTTA and AAAGTTTCGTTGTAAATATA, which resulted in a 13,775 bp deletion beginning at Chromosome 9 position 37,302,836 bp and ending after 37,316,610 bp (GRCm38/mm10). This mutation deletes ENSMUSE00000344794-ENSMUSE00000335669 (exons 6-12) and 12,426 bp of flanking intronic sequence including the splice acceptor and donor and is predicted to cause a change of amino acid sequence after residue 233 and early truncation 1 amino acid later.
