MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] In human, ZIM2 and PEG3 are treated as two distinct genes though they share multiple 5' exons and a common promoter and both genes are paternally expressed (PMID:15203203). Alternative splicing events connect their shared 5' exons either with the remaining 4 exons unique to ZIM2, or with the remaining 2 exons unique to PEG3. In contrast, in other mammals ZIM2 does not undergo imprinting and, in mouse, cow, and likely other mammals as well, the ZIM2 and PEG3 genes do not share exons. Human PEG3 protein belongs to the Kruppel C2H2-type zinc finger protein family. PEG3 may play a role in cell proliferation and p53-mediated apoptosis. PEG3 has also shown tumor suppressor activity and tumorigenesis in glioma and ovarian cells. Alternative splicing of this PEG3 gene results in multiple transcript variants encoding distinct isoforms.

Nature of Mutation
DNA sequencing using the SOLiD technique identified an A to T transversion at position 937 of the Peg3 transcript in exon 9 of 9 total exons. The mutated nucleotide causes a glutamic acid to valine substitution at amino acid 192 of the encoded protein. The mutation has been confirmed by DNA sequencing using the Sanger method (Figure 1).
Protein Function and Prediction
The Peg3 gene is expressed in embryos and the adult brain from the paternal allele only, and encodes a 1571 amino acid protein that belongs to the Krüppel C2H2-type zinc finger family. PEG3 is able to form a homodimer and contains 12 zinc fingers plus a number of internal repeats.  PEG3 is induced during p53 mediated apoptosis in response to DNA damage in cortical neurons and induces apoptosis in cooperation with SIAH1A. PEG3 also interacts with TRAF2 and inhibits tumor necrosis factor (TNF)-induced apoptosis through activation of NF-κB. PEG3 plays a role in regulating maternal behavior and offspring growth (Uniprot Q3URU2).
 
The E192V change does not occur in any predicted domain, but is predicted to be probably damaging by the PolyPhen program.
