Atm^m1Btlr

ENU-induced G to T transversion at base pair 53,516,467 (v38) on chromosome 9, or base pair 20,350 in the GenBank genomic region NC_000075 encoding Atm. The mutation corresponds to residue 1,481 in the mRNA sequence NM_007499 within exon 10 of 64 total exons. The mutation results in substitution of glycine 448 for a premature stop codon (G448*) in the ATM protein. (J:265252)
