ENU-induced A to G transition at base pair 54,046,495 (v38) on chromosome 19, or base pair 1,314 in the GenBank genomic region NC_000085 encoding Adra2a. The mutation corresponds to residue 1,314 in the mRNA sequence NM_007417 within exon 1 of 1 total exons. The mutation results in an aspartic acid to glycine substitution at amino acid 94 (D94G) in the ADRA2A protein. (J:267700)
