Rieger syndrome is a rare genetic disorder characterized by absent or under-developed (hypodontia or partial adontia) teeth, mild craniofacial abnormalities, and various abnormalities of the eye, especially glaucoma. If unaccompanied by other signs and symptoms, the eye abnormalities are referred to as Rieger eye anomalies.
Specialists recognize two genetic forms of Rieger syndrome. Type I occurs as a result of mutations on chromosome 4 and Type II results from mutations on chromosome 13.
