ENU mutagenesis induced an A to G transition at base pair 161,788,164 (v38) on chromosome 1, or base pair 5,651 in the GenBank genomic region NC_000067. The mutation corresponds to residue 332 in the mRNA sequence NM_010177 within exon 1 of 4 total exons. The mutation results in an aspartic acid (D) to glycine (G) substitution at position 41 (D41G).
