ENU-induced T to C transition at base pair 14,891,303 (v38) on chromosome 1, or base pair 27,712 in the GenBank genomic region NC_000067 within the donor splice site of intron 15. The mutation is predicted to result in skipping of the 94-nucleotide exon 15 (out of 27 total exons), resulting in a frame-shifted protein product beginning after amino acid 605, and termination after the inclusion of two aberrant amino acids.
