Insulin-like growth factor (IGF) 2 plays a fundamental role in prenatal growth and development. The IGF2 gene is imprinted, with the paternally inherited copy being active and the maternal copy being silenced in most tissues. During development, the expression of IGF2 is sexually dimorphic in some tissues and this is thought to be involved in the development of some sexually dimorphic features. For example, IGF2 expression is reported to be higher in the male brain co...
