Abstract
Hereditary neuropathy with liability to pressure palsies (HNPP) is an autosomal-dominant focal neuropathy characterized by recurrent entrapment neuropathies. Single members of families with HNPP and brachial plexus involvement have been reported previously. We describe a family with three affected members and in which the only symptom of entrapment was recurrent brachial plexopathy. The diagnosis of HNPP in this family was confirmed by both neurophysiological methods and DNA analysis. The distinction between HNPP and hereditary neuralgic amyotrophy is discussed.
