This allele from project Zfp711-8046J-F4983 was generated at The Jackson Laboratory by injecting Cas9 RNA and 4 guide sequences TCTGATGTTGTCACAGATGA, CTGATGTTGTCACAGATGAT, AGATATCATTAAGTAGTCTT and TTCTACTGTTACCATAAAAA, which resulted in a 439 bp internal deletion beginning at Chromosome X positive strand position 112,614,979 bp, ACAGATGATGGGATAACTCT, and ending after TGTCAAGAGCACTTCTGAAG at 112,615,417 bp (GRCm38/mm10). This mutation deletes 439 bp from exon 3, and is predicted to cause a change of amino acid sequence after residue 56 and early truncation 1 amino acid later. (J:188991)
