Permanent dysphagia in familial amyloid polyneuropathy (ATTRVal30Met).

Gastrointestinal symptoms are frequent in familial amyloid polyneuropathy, mainly resulting from autonomic nervous system involvement. Dysphagia is one of the possible symptoms, although rarely severe or sudden. We describe a case of a sudden onset and severe dysphagia, a rare form of presentation, in a patient whose polyneuropathy was still beeing investigated and turned out to be ATTRVal30Met-polyneuropathy.
