Freeman–Sheldon syndrome

Freeman–Sheldon syndrome (FSS), also termed distal arthrogryposis type 2A (DA2A), craniocarpotarsal dysplasia (or dystrophy), Cranio-carpo-tarsal syndrome, Windmill-Vane-Hand syndrome, or Whistling-face syndrome, was originally described by Freeman and Sheldon in 1938. Freeman–Sheldon syndrome is a rare form of multiple congenital contracture (MCC) syndromes (arthrogryposes) and is the most severe form of distal arthrogryposis (DA).
