ENU mutagenesis induced a T to G transversion at base pair 149,657,319 (v38) on chromosome 4, or base pair 68,648 in the GenBank genomic region NC_000070. The mutation corresponds to residue 1447 in the mRNA sequence NM_001029837 within exon 8 of 23 total exons. The mutation results in a leucine (L) to arginine (R) substitution at position 390 (L390R).
