APOL1 Genetic Testing in African Americans
What this study is about
Recent breakthroughs in medical genetics have discovered that a portion of kidney failure affecting the Black community is mediated by coding variants in a gene called apolipoprotein L1 (APOL1) - and that genetic variants, not race - account for increased risk.
View original scientific description
Recent breakthroughs in medical genetics have discovered that a portion of kidney failure affecting the Black community is mediated by coding variants in a gene called apolipoprotein L1 (APOL1) - and that genetic variants, not race - account for increased risk. For APOL1 genetic testing to be applied in a manner that improves patient care and outcomes, more information is needed regarding associations of genotype with clinical parameters related to kidney health. Further, understanding patient perceptions about knowledge of the results of APOL1 genetic testing, and how that impacts patient engagement with management of hypertension and other renal risk factors, is urgently needed. * In a Phase 1 pilot study, we offered APOL1 genetic testing to Black patients seen in our Hypertension and Nephrology clinics at Saint Louis University, an academic medical center that serves the local urban community, and surveyed patients on attitudes and concerns about APOL1 genetic testing. 144 participants were enrolled in Phase 1. * In the Phase 2 study, we will advance this important work in our community by offering participation to a broader patient base, including patients seen in Internal and Family Medicine clinics, SLU Hospital, as well as to first-degree relatives and spouses of SLUCare participants. This expansion seeks to advance understanding of environment-gene interactions, improve risk prediction, and target management of potentially modifiable risk factors.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
