    Summary
    This locus represents a paternally-expressed imprinted gene that encodes a component of the small nuclear ribonucleoprotein complex, which functions in pre-mRNA processing. Genomic and genetic changes in this region result in growth defects and lethality; the corresponding region in human is the critical region for Prader-Willi Syndrome. Alternative promoter use and alternative splicing result in a multitude of transcript variants encoding the same protein. Transcript variants may be bicistronic and also encode the SNRPN upstream reading frame protein (Snurf) from an upstream open reading frame. In addition, long spliced transcripts for small nucleolar RNA host gene 14 (Snhg14) may originate from the promoters at this locus and incorporate exons shared with this gene.

    1. we found that either knockdown of Nr4a1 or 3, 3'- Diindolylmethane (DIM), an Nr4a1 antagonist, were able to rescue the effects of SNRPN knockdown on neurite outgrowth of embryonic cortical neurons, providing the potential therapeutic methods for SNRPN deletion disorders. We thus concluded that maintaining the proper level of SNRPN is critical in cortical neurodevelopment.

    2. The androgenetic patterns of H19, Snrpn, and Mest were maintained even after differentiation of germline-derived pluripotent stem cells(gPS) into neural stem cells(NSC), whereas the fully unmethylated status of Ndn in SSCs was altered to somatic patterns in gPS cells and gPS-NSCs.
      Title: Epigenetic alteration of imprinted genes during neural differentiation of germline-derived pluripotent stem cells.
    3. These data indicate that oocytes undergo time-dependent demethylation of Snrpn differentially methylated regions during the process of postovulatory aging.
      Title: Loss of methylation imprint of Snrpn in postovulatory aging mouse oocyte.
    4. Oocytes vitrification could lead to the loss of DNA methylation of imprinted genes (H19, Peg3, and Snrpn) in mouse blastocysts, which is mainly caused by the reductions of DNMTs after vitrification of oocytes.

    5. These results support a model in which transcription from the Snrpn upstream exons directs the maternal imprint at the PWS-IC
      Title: Transcription is required to establish maternal imprinting at the Prader-Willi syndrome and Angelman syndrome locus.
    6. Snrpn gene is imprinted, with monoallelic expression from the paternal allele in brain and heart.
      Title: Structure of the imprinted mouse Snrpn gene and establishment of its parental-specific methylation pattern.
    7. The tissue-specific methylation of the mouse conserved activator sequence and its methylation-sensitive enhancer activity may control expression of imprinting center transcripts, establishing and/or maintaining imprinting in the Snrpn locus.
      Title: Developmentally dynamic changes of DNA methylation in the mouse Snurf/Snrpn gene.
    8. the ATG-to-AAG mutation causes a 15-fold or more increase in translation of the downstream ORF in two fusion constructs, and it is likely that similar translational control affects the normal Snurf-Snrpn transcript as well
      Title: Evidence for translational regulation of the imprinted Snurf-Snrpn locus in mice.
    9. Mouse model for Prader-Willi syndrome. Deletion of Snrpn gene and putative imprinting-centre is associated with absent expression of the imprinted genes Zfp127, Ndn and Ipw, and phenotypes similar to those found in Prader-Willi infants.
