Carpal tunnel syndrome is an entrapment neuropathy of the median nerve characterized by paresthesias in the district of the median nerve. Familial carpal tunnel syndrome is an extremely rare form with bilateral symptom that is frequently associated with inherited systemic disorders such as mucopolysaccharidosis, mucolipidosis, amyloidosis, collagen vascular disease or hereditary liability to pressure palsies. The cause of the disease is the compression of the median nerve by thickened transverse carpal ligament. Mutations in transthyretin, a gene that plays a role in deposition of amyloid, have been reported.
