ENU mutagenesis induced a C to A transversion at base pair 134,747,620 (v38) on chromosome 1, or base pair 101,057 in the GenBank genomic region NC_000067. The mutation corresponds to residue 1,589 in the mRNA sequence NM_009307 within exon 10 of 10 total exons. The mutation results in an alanine (A) to aspartic acid (D) substitution at position 403 (A403D). (J:224662)
