ENU mutagenesis induced a C to T transition at base pair 85,621,275 (v38) on chromosome 6, or base pair 33,779 in the GenBank genomic region NC_000072 encoding Alms1. The mutation corresponds to residue 3,197 in the mRNA sequence NM_145223 within exon 8 of 23 total exons. The mutated nucleotide converts glutamine 1028 of the ALMS1 protein to a stop codon.
