Fatigue. Swollen Ankles. Carpal Tunnel. Tingling Hands or Feet.
Too often, Black adults chalk these symptoms up to aging, hard work, or diabetes. But for many, these symptoms are signs of a little-known yet life-threatening disease: amyloidosis.

What Is Amyloidosis?
Amyloidosis occurs when abnormal proteins, called amyloid, build up in organs and tissues, interfering with their normal function. The most common form affecting Black Americans is transthyretin amyloidosis (ATTR). In ATTR, amyloid proteins stiffen the heart muscle, making it harder to pump blood effectively and leading to heart failure (Mayo Clinic).
Why Black Americans Are at Higher Risk
One genetic change — the V122I mutation in the transthyretin (TTR) gene — is carried by about 3–4% of Black Americans, compared to almost no other groups (NIH).
- By age 60: Carriers have a 50% chance of developing ATTR cardiomyopathy.
- By age 80: That risk jumps to 90%.

Yet most don’t know they carry the mutation. And many doctors still misdiagnose ATTR as high blood pressure, arthritis, or “just getting older” (American Heart Association).

Silent Symptoms You Shouldn’t Ignore
Amyloidosis is often called a “silent killer” because symptoms are vague or mistaken for other conditions. Warning signs include:
- Carpal tunnel syndrome (often years before diagnosis)
- Numbness, tingling, or burning in hands or feet (neuropathy)
- Swollen ankles or legs
- Shortness of breath or fatigue
- Irregular heartbeat or chest pain
- Unexplained weight loss or gastrointestinal issues
The Power of Genetic Testing
Genetic testing can identify the V122I mutation before symptoms start, making it one of the most powerful tools for Black families. Testing helps:
- Detect carriers early
- Guide preventive monitoring and treatment
- Inform family members about their risk
Ask your doctor specifically about genetic testing for amyloidosis. Don’t wait for heart failure to appear.
Starting Family Conversations About Genetic Risk
Talking about inherited conditions can feel heavy — especially when fear or guilt enters the room.
Use these prompts to start the conversation and replace silence with shared strength:
- “Have you ever noticed anyone in our family with heart problems, swelling, or carpal tunnel?”
→ Opens the door to family history without accusation.
- “I just learned that amyloidosis can run in families, especially among Black folks. Would you be open to learning more together?”
→ Centers curiosity and shared learning instead of fear.
- “If one of us had the gene, what support or information would make it easier to talk about?”
→ Shifts focus from guilt to support and solutions.
- “Our health is family history in motion — what can we do now to protect the next generation?”
→ Encourages action, not shame.
- “How can we make sure everyone in our family — especially the men — feels comfortable getting checked?”
→ Normalizes testing and bridges gender gaps in health conversations.
Remember: Knowing your genetic risk doesn’t define your future — it helps shape a healthier one. When families talk, fear loses power, and generations gain strength.

Treatments and Hope
Amyloidosis once meant little hope. Today, there are FDA-approved treatments that slow progression:
- Medications: Tafamidis (Vyndaqel), patisiran, inotersen
- Devices: Pacemakers, defibrillators
- Transplants: Heart or liver in severe cases
Lifestyle changes and symptom management also improve quality of life. Early detection opens the door to these options (Amyloidosis Foundation).
3 Questions to Ask Your Doctor
- Could my fatigue, swelling, or carpal tunnel be related to amyloidosis?
- Should I be tested for the V122I genetic mutation?
- If diagnosed, what treatments or support groups are available for me and my family?
Where to Get Help in Cincinnati
If you live in Greater Cincinnati and suspect amyloidosis, these providers have experience with heart failure, genetics, and rare disease care:
- University of Cincinnati Medical Center – UC Health Amyloidosis Clinic (Cardiology & Hematology)
