What is ATTR amyloidosis?
ATTR amyloidosis is the most common familial form of amyloidosis and is caused mainly by non-synonymous mutations in the transthyretingene (TTR; Chr. 18q12.1; 147 amino acids), which lead to instability of the protein's tetrameric structure.

What are the two types of amyloidosis that are most likely to damage the heart?
The two kinds most likely to damage the heart are light chain amyloidosis (AL) and transthyretin amyloidosis (ATTR). Treatment depends on the specific subtype of amyloidosis. It may involve medication, chemotherapy and stem cell transplantation.
How to diagnose amyloidosis?
To confirm a diagnosis of cardiac amyloidosis, you will need either a cardiac biopsy or technetium pyrophosphate scan. A cardiac biopsy involves taking a small sample of heart tissue that the doctor examines under the microscope.
What is a technetium pyrophosphate scan?
A technetium pyrophosphate scan is similar to an MRI in that it gives a picture of the heart. A dye is injected before the scan and will cause transthyretin amyloidosis to “light up.”. If either test indicates TTR amyloidosis, genetic testing is recommended to confirm the subtype. Other tests that might be recommended:
How to treat TTR?
Treatment depends on the subtype and may involve a combination of these approaches: 1 Medication to stabilize the TTR protein (for ATTR, not AL) 2 Medication to “silence” the TTR gene and prevent the body from producing the TTR protein (for ATTR, not AL) 3 Medications to reduce swelling or control irregular heartbeat 4 A pacemaker to regulate the heartbeat 5 Chemotherapy (for AL, not for ATTR) 6 Auto stem cell transplant (for AL, not for ATTR) 7 Clinical trial participation to test new therapies.

What drugs can cause amyloidosis?
For certain types of amyloidosis, drugs such as patisiran (Onpattro) and inotersen (Tegsedi) can interfere with the commands sent by faulty genes that create amyloid. Other drugs, such as tafamidis (Vyndamax, Vyndaqel) and diflunisal, can stabilize bits of protein in the bloodstream and prevent them from getting transformed into amyloid deposits.
Why is it important to know early diagnosis of amyloidosis?
Amyloidosis is often overlooked because the signs and symptoms can mimic those of more-common diseases. Early diagnosis can help prevent further organ damage. Precise diagnosis is important because treatment varies greatly, depending on your specific condition.
What to do if your heart is affected?
