General annotation (Comments)

Function	Could be involved in ear development.
Involvement in disease	Defects in FGF3 are a cause of deafness with labyrinthine aplasia, microtia and microdontia (LAMM) [MIM:610706]; also known as congenital deafness with inner ear agenesis, microtia and microdontia. LAMM consists of a unique autosomal recessive syndrome characterized by type I microtia, microdontia, and profound congenital deafness associated with a complete absence of inner ear structures (Michel aplasia). Ref.3 Ref.4
Sequence similarities	Belongs to the heparin-binding growth factors family.
