MGI Phenotype FUNCTION: This gene encodes a transcription factor involved in apoptosis. The encoded protein functions in cell cycle progression and plays a role in chromosomal stability. This protein regulates the self-renewal of embryonic stem cells. Disruption of this gene in mice causes symptoms similar to myelodysplastic/myeloproliferative diseases in humans. Mice lacking this gene show severely reduced fertility. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Apr 2014]
PHENOTYPE: Mice homozygous for a knock-out allele exhibit severely reduced fertility; about one-half develop a transplantable disease characterized by anomalies in spleen, bone marrow, and peripheral blood and including anemia and various symptoms typical of myeloid dysplasia or myeloid proliferation.

Nature of Mutation
DNA sequencing using the SOLiD technique identified a T to C transition at position 3263 of the Dido1 transcript in exon 13 of 17 total exons.  Multiple transcripts of Dido1 gene are displayed on Ensembl. The mutated nucleotide causes a methionine to threonine substitution at amino acid 979 of isoform 3 of the encoded protein. The mutation has been confirmed by DNA sequencing using the Sanger method (Figure 1).
Protein Function and Prediction
The Dido1 gene encodes at least three protein isoforms, Dido1, Dido2, and Dido3. Dido3 is the largest and most dominantly expressed protein isoform with 2256 amino acids.  The Dido proteins contain one PHD-type zinc finger at amino acids 265-319, and a transcription elongation factor S-II (TFIIS) central domain at amino acids 667-787. PHD-type zinc fingers are typically involved in chromatin-mediated transcriptional regulation. Dido1 is a putative transcription factor that is upregulated during apoptosis, and translocates to the nucleus in response to pro-apoptotic stimuli. It is weakly pro-apoptotic when overexpressed (Uniprot Q8C9B9). Mice homozygous for a null allele of Dido1 exhibit myelodysplasia and a myeloproliferative disorder. Humans with similar disorders display abnormalities in Dido expression. Dido3 associates with centrosomes, and a specific disruption in Dido3 leads to supernumerary centrosomes, and a failure to maintain mitotic arrest resulting in enhanced aneuploidy in Dido mutant cells.
 
The M979T change is predicted to be possibly damaging by the PolyPhen program.
