ENU mutagenesis induced a T to C transition at base pair 65,462,915 (v38) on chromosome 18, or base pair 31,947 in the NC_000084 GenBank genomic region within the donor splice site of intron 10 (2 base pairs from exon 10). The effect of the mutation at the cDNA and protein level have not examined, but the mutation is predicted to result in skipping of the 178-base pair exon 10 (out of 16 total exons), resulting in a frame-shift and coding of 13 aberrant amino acids followed by a premature stop codon within exon 11 (after amino acid 418).
