ENU-induced A to G transition at base pair 11,226,986 (v38) on chromosome 2, or base pair 55,083 in the GenBank genomic region NC_000068 within the donor splice site of intron 2 (Transcript_ID = ENSMUST00000028118.8). The effect of the mutation at the cDNA and protein level have not examined, but the mutation is predicted to result in the use of a cryptic site in exon 1 (out of 16 total exons; Transcript_ID = ENSMUST00000102970.4). Use of the cryptic site in exon 1 would result in a 14-base pair deletion in exon 1 and a frame-shifted protein product beginning after amino acid 34 and terminating after the inclusion of 20 aberrant amino acids.
