Lethal congenital contractural syndrome (LCCS) is a heterogeneous group of disorders characterized by congenital nonprogressive joint contractures with a severe form of arthrogryposis. LCCS is inherited in an autosomal recessive manner. It has a worldwide incidence, but it is more common in isolated populations, such as Finland and the Bedouin community in Israel. Several mutations associated with LCCS have been reported.

Congenital hypomyelinating neuropathy (CHN) is a rare congenital neuropathy, often accompanied by arthrogryposis, that is characterized by prenatal onset, areflexia, hypotonia, hypomyelination, and slowed nerve conduction velocities. Previous reports of genetic analyses of patients have described mutations in genes known to be important in myelination.
