Quick Reference

An imprinted gene that encodes two polypeptides (i.e. is bicistronic), the SmN splicing factor, (small nuclear ribonucleoprotein polypeptide N) which is involved in RNA processing, and the SNRPN upstream reading frame (SNURF) polypeptide. Deletion of the paternal copy leads to Prader–Willi syndrome, that of the maternal copy to Angelman's syndrome.
