Synonym(s): Duane syndromeDuane radial ray syndrome An autosomal dominant condition (MIM:102490) characterised by limited external rotation of the eyes and retraction with inward rotation, and by radial-ray-type bone defects in the hands (e.g., malformed or absent thumbs, extra thumb or finger-like thumb) and forearms (e.g., absence of one or more forearm bones); it may be accompanied by renal defects. Molecular pathology DRRS is caused by mutations of SALL4, which encodes a zinc finger transcription factor thought to play a role in musculoskeletal embryogenesis.Duane syndrome (dwān) [Alexander Duane, U.S. ophthalmologist, 1858–1926] A disorder of eye movement in which the affected eye does not move centrally or temporally in a normal manner and pulls into the orbit on adduction.Duane, Alexander, U.S. ophthalmologist, 1858-1926.
