โœฆ Synopsis


Hereditary amyloidosis with early and prominent peripheral nerve involvement is often designated familial amyloid polyneuropathy (FAP). The abnormality usually lies in the transthyretin (TTR) gene. We describe a patient with a tyr77 TTR gene mutation who presented with sensorimotor polyneuropathy but no other systemic symptoms of amyloidosis. This is one of a few documented cases of the tyr77 mutation in North America. The clinical and electrophysiologic features of this unusual cause of sensorimotor polyneuropathy are discussed.

In 1975, Lessell et a1 ( I ) described "scalloping" of the pupils, a unique pupillary sign in 2 patients with aiutosomal dominant inherited familial amyloid pdyneuropathy (FAP). Although apparently pathognomonic, the sensitivity of this sign in a larger population of FAP patients is unknown. We ther

Familial amyloid polyneuropathy is an autosomal dominant disorder in which the liver produces a variant prealbumin that is deposited along nerves, leading to a progressive and fatal polyneuropathy that begins in the third decade of life. Liver transplantation has been the only successful treatment t
