ENU mutagenesis induced a single nucleotide deletion of a C at 96140630 or 96140631 bp (NCBI v38) on chromosome 9 at position 607 or 608 bp within transcript Ensembl ENSMUST00000085217. This mutation causes a frameshift and subsequent coding of one unrelated amino acid (p.Thr174Pro) followed by a premature stop (p.Leu175Stop) in the 516 (variant 1) or 534 (variant 2) amino acid peptide.
