Axenfeld-Rieger syndromeAn autosomal dominant condition (OMIM:180500) characterised by hypodontia, defect of the anterior chamber of the eye, myotonic dystrophy and anal stenosis.
Type-1 Axenfield-Rieger syndrome is caused by a mutation in a homeobox transcription factor gene PITX2; a second type of A-R syndrome has a defect that maps to chomosome 14q13, RIEG2.
