Progression of cardiomyopathy and neuropathy after liver transplantation in a patient with familial amyloidotic polyneuropathy caused by tyrosine-77 transthyretin variant.
Familial amyloidotic polyneuropathy is an inherited form of amyloidosis associated with a mutant form of a protein called transthyretin. The Methionine-30 variant is the most frequent mutation observed. This disorder is caused by deposition of this protein as amyloid in several organs, such as the heart, kidneys, and peripheral nervous system. The disease is always progressive and fatal, and patients die 7 to 10 years after the onset of symptoms. Liver transplantation is at present the only choice for these patients because it provides improvement of symptoms and/or stops progression of the disease in most patients. We report the case of a patient who showed clear progression of cardiomyopathy and neuropathy after liver transplantation.
