ENU mutagenesis induced an A to C transversion at 47016337 bp on chromosome 14 within Samd4 (Fig. 3B). The mutation occurs at 994 bp within the transcript (Vega OTTMUST00000057924) and leads to a
histidine to proline substitution at amino acid 86 of the 711 amino acid isoform 1 and the 623 amino acid isoform 2.
