ENU-induced A to T transversion at base pair 60,963,928 (v38) on chromosome 18, or base pair 38,352 in the GenBank genomic region NC_000084 encoding Camk2a. The mutation corresponds to residue 1,096 in the mRNA sequence NM_177407 within exon 13 of 18 total exons. The mutation results in substitution of lysine 317 to a premature stop codon (K317*) in the CaMKII protein. (J:265120)
