IGF2 (human)

IGF2 The insulin-like growth factors possess growth-promoting activity. In vitro, they are potent mitogens for cultured cells. IGF-II is influenced by placental lactogen and may play a role in fetal development. Epigenetic changes of DNA hypomethylation in IGF2 are a cause of Silver-Russell syndrome (SRS). A clinically heterogeneous condition characterized by severe intrauterine growth retardation, poor postnatal growth, craniofacial features such as a triangular shaped face and a broad forehead, body asymmetry, and a variety of minor malformations. The phenotypic expression changes during childhood and adolescence, with the facial features and asymmetry usually becoming more subtle with age. Belongs to the insulin family. 2 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
