ENU mutagenesis induced an A to T transversion at base pair 111,495,791 (v38) on chromosome 6, or base pair 850,334 in the GenBank genomic region NC_000072. The mutation corresponds to residue 2,860 in the NM_177328 mRNA sequence in exon 9 of 10 total exons and residue 2,877 in the ENSMUST00000071076 cDNA sequence in exon 9 of 11 total exons. The mutation results in substitution of lysine 864 (K864) for a premature stop codon (K864*) in all isoforms. (J:224658)
