ENU-induced T to A transversion at base pair 44,990,504 (v38) on chromosome 11, or base pair 372,405 in the GenBank genomic region NC_000077 within intron 11 (12 base pairs from exon 12. The effect of the mutation at the cDNA and protein levels has not been examined, but the mutation is predicted to result in the use of a cryptic site in intron 11, resulting in a 31-base pair insertion of intron 11. The insertion would cause a frame-shifted protein product beginning after amino acid 376 of the protein and premature termination after the inclusion of 14 aberrant amino acids.
