Genes affected
IGF2-AS (HGNC:14062): (IGF2 antisense RNA) This gene is expressed in antisense to the insulin-like growth factor 2 (IGF2) gene and is imprinted and paternally expressed. It is thought to be non-coding because the putative protein is not conserved and translation is predicted to trigger nonsense mediated decay (NMD). Transcripts from this gene are produced in tumors and may function to suppress cell growth. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Nov 2015]
IGF2 (HGNC:5466): (insulin like growth factor 2) This gene encodes a member of the insulin family of polypeptide growth factors, which are involved in development and growth. It is an imprinted gene, expressed only from the paternal allele, and epigenetic changes at this locus are associated with Wilms tumour, Beckwith-Wiedemann syndrome, rhabdomyosarcoma, and Silver-Russell syndrome. A read-through INS-IGF2 gene exists, whose 5' region overlaps the INS gene and the 3' region overlaps this gene. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2010]
