FG, fg, or Fg may refer to:
Fibroblast growth factor 21 is a protein that in mammals is encoded by the FGF21 gene. The protein encoded by this gene is a member of the fibroblast growth factor (FGF) family and specifically a member of the endocrine subfamily which includes FGF23 and FGF15/19. FGF21 is the primary endogenous agonist of the FGF21 receptor, which is composed of the co-receptors FGF receptor 1 and β-Klotho.
FG syndrome (FGS; also known as Opitz–Kaveggia syndrome) is a rare genetic syndrome caused by one or more recessive genes located on the X chromosome and causing physical anomalies and developmental delays.
FGF1, also known as acidic fibroblast growth factor (aFGF), is a growth factor and signaling protein encoded by the FGF1 gene.
Fibroblast growth factor receptor oncogene partner 2 (FGFR1OP2) was identified in a study on myeloproliferative syndrome (EMS).
Fgura (Maltese: Il-Fgura, Italian: Figura) is a town in the South Eastern Region of Malta. It has a population of 11,670 as of March 2014. Its northern fringes are bordered by the Cottonera Lines of fortifications while it merges with the towns of Żabbar to the east and Paola and Tarxien to the West.
Glia-activating factor is a protein that in humans is encoded by the FGF9 gene.
Fibrinogen-like protein 2, also known as FGL2, is a protein which in humans is encoded by the FGL2 gene.
