Paternal<i>GNAS</i>Mutations Lead to Severe Intrauterine Growth Retardation (IUGR) and Provide Evidence for a Role of XLαs in Fetal Development

Abstract

These data indicate that a paternally derived GNAS transcript, possibly XLαs, is required for normal fetal growth and development and that this transcript affects placental functions. Thus, similar to other imprinted genes, GNAS controls growth and/or fetal development.
