ENU mutagenesis induced a C to A transversion at base pair 60308056 (v38) on Chromosome 10, equivalent to base pair 388435 in the GenBank genomic region NC_000076 encoding Cdh23. The mutation corresponds to residue 9176 in the NM_023370.3 mRNA sequence in exon 62 of 71 total exons. The mutation also corresponds to residue 9710 in the NM_001252635 mRNA sequence in exon 61 of 70 total exons. The mutation results in a tyrosine (Y) to premature stop codon (*) substitution at amino acid residue 2923 in ENSMUSP00000101101 or residue 2921 in ENSMUSP00000101104.
