Arthrogryposis multiplex congenita (AMC) is not inherited in most cases; however, a genetic cause can be identified in about 30% of affected people. It can be a component of many different genetic conditions, including those caused by a single gene change or a chromosomal abnormality, such as trisomy 18. Genetic conditions sometimes associated with AMC include some connective tissue disorders; muscle disorders such as muscular dystrophies or congenital myopathies; and certain mitochondrial disorders. Depending on the underlying genetic cause, it may be inherited in an autosomal recessive, autosomal dominant or X-linked manner. Some cases are thought to have multifactorial inheritance, which means that both genetic and environmental factors may play a role in causing the condition.
