APOL1 Kidney Disease: Are You at Risk?

Did you know that kidney disease disproportionately affects the Black community? While high blood pressure and diabetes are well-known contributors, there’s another crucial factor at play: genetics. APOL1-Mediated Kidney Disease (AMKD) is a specific form of kidney disease linked to a gene variant found in people of African ancestry, and understanding your risk is vital for protecting your health.

The Origins of the APOL1 Gene

We all inherit two copies of the APOL1 gene, one from each parent. This gene produces a protein crucial for our immune system’s fight against infections. Thousands of years ago in Sub-Saharan Africa, specific variants of this gene evolved to offer protection against the parasite that causes African sleeping sickness. However, these protective variants also introduced a vulnerability over time.

Individuals who inherit two copies of these high-risk APOL1 variants face a significantly increased chance of developing kidney disease. These variants can damage the kidney’s filtering units, leading to protein leakage into the urine and a gradual decline in kidney function. Because these variants originated in sub-Saharan Africa, AMKD primarily impacts individuals of recent African ancestry, including those who identify as Black, African American, Afro-Caribbean, or Latino. It’s estimated that about 6 million African Americans carry these high-risk variants.

Recognizing the Symptoms of AMKD

Kidney disease is often called a “silent condition” because symptoms may not appear until the disease is quite advanced. However, being aware of the warning signs can lead to earlier detection. Common symptoms include:
– Fatigue and low energy
– Swelling in the feet and ankles
– Foamy or bubbly urine

If you notice any of these changes, it’s crucial to consult a healthcare professional. Discussing these symptoms with your doctor, especially if you have a family history of kidney disease, is essential for determining if there are signs of kidney issues, including AMKD.

Diagnosis and Treatment Pathways

Doctors typically use simple blood and urine tests to assess kidney function and detect damage. While these tests can diagnose kidney disease, they don’t always reveal the specific cause, meaning you could have kidney disease without knowing if it’s AMKD. The only definitive way to confirm if your kidney disease is linked to APOL1 is through genetic testing, which usually involves a simple blood, saliva, or cheek swab.

Given that kidney disease can have a hereditary component, open conversations about health history within families are vital. Talking to relatives about any history of kidney disease or dialysis can provide valuable information for your doctor, helping them guide your care and determine if genetic testing is appropriate for you.

Alonzo Mourning’s Journey and Advocacy

Basketball Hall-of-Famer Alonzo Mourning knows the impact of kidney disease firsthand. Diagnosed with focal segmental glomerulosclerosis (FSGS), a form of AMKD, at the height of his career, he eventually required a kidney transplant. Now, two decades later, Mourning is a prominent advocate for AMKD awareness through the “Power Forward Together” campaign, partnering with Vertex Pharmaceuticals. He bravely shares his story to encourage others in the Black community to be proactive about their kidney health.

Raising awareness about AMKD is the first step toward better health outcomes for Black Americans who may be at an increased risk for or living with kidney disease. — BlackDoctor.com

Taking Charge of Your Kidney Health

Understanding your genetic risks and family history is a powerful first step toward better health. Knowing your potential risk for AMKD can empower you to take control. Make a plan to see your doctor regularly, familiarize yourself with the signs of kidney disease, and discuss whether APOL1 genetic testing might be right for you.
