arthrogryposis multiplex congenita (MONDO_0015168, a Monarch Disease Ontology entry) (AMC) is a group of disorders characterized by congenital limb contractures. It manifests as limitation of movement of multiple limb joints at birth that is usually non-progressive and may include muscle weakness and fibrosis. AMC is always associated with decreased intrauterine fetal movement which leads secondarily to the contractures. Also known as: AMC, Arthromyodysplasia congenita, congenital arthromyodysplasia, multiple congenital arthrogryposis, myodysplasia.
