ENU mutagenesis induced a T to A transition at base pair 65,458,200 (v38) on chromosome 18, or base pair 27,332 in the NC_000071 GenBank genomic region. The mutation corresponds to residue 1,216 in the mRNA sequence NM_172833 within exon 9 of 16 total exons. The mutation results in an asparagine (N) to lysine (K) substitution at position 347 (N347K) in the protein. (J:224671)
