Overview


Axenfeld-Rieger syndrome refers to a spectrum of developmental eye disorders. Common eye symptoms include cornea defects, iris defects, and glaucoma. About 50% of affected individuals become blind from glaucoma. Other associated developmental defects commonly involve the teeth and facial bones. [1][2][3][4][5].

There are three types of Axenfeld-Rieger syndrome, which are distinguished by their genetic cause. Axenfeld-Rieger syndrome type 1 is caused by mutations in the PITX2 gene and Axenfeld-Rieger syndrome type 3 is caused by mutations in the FOXC1 gene.[5][6] The gene that causes Axenfeld-Rieger syndrome type 2 has not yet been identified, but it is located on chromosome 13.[7] Axenfeld-Rieger syndrome has an autosomal dominant pattern of inheritance.[5][6][7]
