Familial transthyretin amyloidosis (FTA) is a rare inherited condition characterized by abnormal build-up of a protein called amyloid in the body’s organs and tissues . Symptoms start in adulthood and get worse over time. Signs and symptoms depend on where the amyloid protein is building up.
What is gelsolin amyloidosis?
Hereditary gelsolin amyloidosis (HGA) is an autosomally dominantly inherited form of systemic amyloidosis, characterized mainly by cranial and sensory peripheral neuropathy, corneal lattice dystrophy, and cutis laxa.
What type of amyloidosis is hereditary?
The most common type of hereditary amyloidosis is transthyretin amyloidosis (ATTR), a condition in which the amyloid deposits are most often made up of the transthyretin protein which is made in the liver.
Does amyloidosis run in families?
ATTR amyloidosis can run in families and is known as hereditary ATTR amyloidosis. People with hereditary ATTR amyloidosis carry mutations in the TTR gene. This means their bodies produce abnormal TTR proteins throughout their lives, which can form amyloid deposits. These usually affect the nerves or the heart, or both.
What are the symptoms of hereditary amyloidosis?
Signs and symptoms of amyloidosis may include:
- Swelling of your ankles and legs.
- Severe fatigue and weakness.
- Shortness of breath with minimal exertion.
- Unable to lie flat in bed due to shortness of breath.
- Numbness, tingling or pain in your hands or feet, especially pain in your wrist (carpal tunnel syndrome)
Is there a cure for hereditary amyloidosis?
The only treatment that can potentially cure familial amyloidosis is a liver transplantation. This is because the amyloid protein that causes this condition is produced in the liver.
What is the work of gelsolin?
Gelsolin is a cytoplasmic, calcium-regulated, actin-modulating protein that binds to the barbed ends of actin filaments, preventing monomer exchange (end-blocking or capping). It can promote nucleation (the assembly of monomers into filaments), as well as sever existing filaments.
How do you test for hereditary amyloidosis?
Blood and urine tests will be done to help your doctor determine the diagnosis of amyloidosis. These tests can also help to show which organs are involved and how much damage they may have. In addition, a tissue biopsy will be performed. This involves the removal of a small sample of tissue for lab examination.
How do you test for familial amyloidosis?
If you have a parent with one of the hereditary amyloidosis types, you can be tested to see if you’ve inherited the same amyloid gene. This DNA test is done by a blood sample.
How is hereditary amyloidosis treated?
Treatment. The only treatment that can potentially cure familial amyloidosis is a liver transplantation. This is because the amyloid protein that causes this condition is produced in the liver.
What is the life expectancy of a person with amyloidosis?
On average, people with familial ATTR amyloidosis live for 7 to 12 years after they get their diagnosis, according to the Genetic and Rare Diseases Information Center. A study published in the journal Circulation found that people with wild-type ATTR amyloidosis live an average of about 4 years after diagnosis.
What organisms have gelsolin?
Cellular gelsolin, found within the cytosol and mitochondria, has a closely related secreted form, Plasma gelsolin, that contains an additional 24 AA N-terminal extension….Gelsolin (cellular)

Familial amyloidosis, Finnish type, or gelsolin amyloidosis, is a condition characterized by abnormal deposits of amyloid protein that mainly affect the eyes, nerves and skin.
Where can I find information on familial amyloidosis (fluvoidosis Finnish type)?
Genetics Home Reference (GHR) contains information on Familial amyloidosis, Finnish type. This website is maintained by the National Library of Medicine. The National Organization for Rare Disorders (NORD) has a report for patients and families about this condition.
What is amyamyloidosis awareness?
Amyloidosis Awareness is an illustrated booklet for patients and physicians developed by Amyloidosis Support Groups Inc. Versions of the booklet are also available in Spanish and Portuguese . Genetics Home Reference (GHR) contains information on Familial amyloidosis, Finnish type.
What are the symptoms of amyloidosis in the eye?
Eye symptoms typically begin first. The amyloid deposits cloud the cornea, often leading to vision impairment. [1] Other eye symptoms may include dryness, irritation and light sensitivity. Affected individuals may eventually develop cataracts and glaucoma. [2]
