<unk>  is a type of distal arthrogryposis, related to distal arthrogryposis type 1 (DA1). In 1996, more strict criteria for the diagnosis of<unk>  were drawn up, assigning<unk>  as distal arthrogryposis type 2A (DA2A). On the whole, DA1 is the least severe; DA2B is more severe with additional features that respond less favourably to therapy. DA2A<unk>  is the most severe of the three, with more abnormalities and greater resistance to therapy.<unk>  has been described as a type of congenital myopathy. In March 2006, Stevenson et al. published strict diagnostic criteria for distal arthrogryposis type 2A (DA2A) or<unk> . These included two or more features of distal arthrogryposis: microstomia, whistling-face, nasolabial creases, and 'H-shaped' chin dimple.
