ENU mutagenesis induced a T to A transversion at base pair 56,423,352 (v38) on chromosome 5, or base pair 29,583 in the GenBank genomic region NC_000071. The mutation corresponds to residue 1,882 in the NM_008861 mRNA sequence in exon 7 of 15 total exons. The mutation results in a tryptophan (W) to arginine (G) substitution at position 568 (W568R).
