This allele was generated at The Jackson Laboratory by electroporating Cas9 protein and 2 guide sequences GGGATCTGTGAAGGTCGACT and CATTACATACAAGATCATTA, which resulted in a 467 bp deletion beginning at Chromosome 10 position 83,300,925 bp and ending after 83,301,391 bp (GRCm38/mm10). This mutation deletes ENSMUSE00000295326 (exon 5) and 322 bp of flanking intronic sequence including the splice acceptor and donor and is predicted to cause a change of amino acid sequence after residue 245 and early truncation 1 amino acid later.
