ENU-induced T to A transversion at base pair 13,648,802 (v38) on chromosome 13, or base pair 58,463 in the GenBank genomic region NC_000079 for the gene. The mutation corresponds to residue 4,539 in the mRNA sequence NM_010748 within exon 12 of 53 total exons. The mutation results in substitution of leucine 1453 to a premature stop codon (L1453*) in the protein. (J:255206)
