Description : Arthrogryposis multiplex congenita (AMC) is a heterogeneous group of disorders characterized
by congenital nonprogressive joint contractures, with a worldwide incidence of 1 in
3,000 live births. AMC can occur in the upper or lower limbs and/or the vertebral
column, leading to various degrees of flexion or extension limitations evident at
birth (summary by Markus et al., 2012). There is also a distal form of arthrogryposis
multiplex congenita (see DA1A, 108120) and a lethal congenital form (see LCCS1, 253310).;
