There are three major forms of familial transthyretin amyloidosis, which are distinguished by their symptoms and the body systems they affect. The neuropathic form of transthyretin amyloidosis primarily affects the peripheral and autonomic nervous systems, resulting in peripheral neuropathy and difficulty controlling bodily functions. The leptomeningeal form of transthyretin amyloidosis primarily affects the central nervous system. The cardiac form of transthyretin amyloidosis affects the heart.

The Human Phenotype Ontology (HPO) provides the following list of features that have been reported in people with this condition. Much of the information in the HPO comes from Orphanet, a European rare disease database. If available, the list includes a rough estimate of how common a feature is (its frequency). Frequencies are based on a specific study and may not be representative of all studies. You can use the MedlinePlus Medical Dictionary for definitions of the terms below.
|Signs and Symptoms||Approximate number of patients (when available)|
|Amyloid deposition in the vitreous humor||-|
|Orthostatic hypotension due to autonomic dysfunction||-|
|Peripheral axonal neuropathy||-|
Treatment for familial amyloid polyneuropathy may include:
In terms of preventing some signs and symptoms associated with the condition, orthotopic liver transplantation (OLTX) is reportedly the only effective therapy for the neuropathy associated with familial transthyretin (TTR) amyloidosis. This type of liver transplantation involves replacing the recipient liver with a donor liver. This procedure removes the main production site of the abnormal
Research helps us better understand diseases and can lead to advances in diagnosis and treatment. This section provides resources to help you learn about medical research and ways to get involved.
Support and advocacy groups can help you connect with other patients and families, and they can provide valuable services. Many develop patient-centered information and are the driving force behind research for better treatments and possible cures. They can direct you to research, resources, and services. Many organizations also have experts who serve as medical advisors or provide lists of doctors/clinics. Visit the group’s website or contact them to learn about the services they offer. Inclusion on this list is not an endorsement by GARD.
Living with a genetic or rare disease can impact the daily lives of patients and families. These resources can help families navigate various aspects of living with a rare disease.
These resources provide more information about this condition or associated symptoms. The in-depth resources contain medical and scientific language that may be hard to understand. You may want to review these resources with a medical professional.
The XVIth International Symposium on Amyloidosis
May 31, 2017
XIV International Symposium on Amyloidosis
Sunday, April 27, 2014 -
Friday, May 2, 2014
Location: Indianapolis, Indiana
Description: One important goal is to foster interactions between investigators who do not meet regularly outside of this event. Through this conference, experts can share unpublished scientific and clinical information about rare diseases that are hard to treat. A second crucial goal is to stimulate interest in a new generation of investigators by providing generous support for at least 10 junior-level researchers to attend the meeting, giving out awards for the most promising clinical research, the best poster, and the best oral presentation by young investigators, and providing childcare options.
