Description
This gene encodes a member of the insulin family of polypeptide growth factors that is involved in development and growth. It is an imprinted gene and is expressed only from the paternally inherited allele. It is a candidate gene for eating disorders. There is a read-through, INS-IGF2, which aligns to this gene at the 3 region and to the upstream INS gene at the 5 region. Alternatively spliced transcript variants, encoding either the same or different isoform, have been found for this gene
