Communicating Risk Alleles in Kidney Genes: Lessons from APOL1 and New Discoveries of Risk Alleles

Abstract

Effective communication of genetic risk alleles, particularly APOL1 renal risk variants, is essential for enhancing patient comprehension, guiding clinical decision-making, and ensuring equitable health care. This review explores the communication and implications of risk alleles in kidney-related genes, emphasizing the need for genetic training for nephrologists, expanded genetic counseling services, and multidisciplinary collaboration to optimize test interpretation and patient-centered care. Increasing ancestral diversity in genetic databases remains critical for refining risk assessments and minimizing uncertainty in result interpretation. Additionally, addressing concerns regarding genetic discrimination through legal protections is necessary to promote ethical use of genetic information. Collaborating with experts in risk communication and engaging community members, as exemplified by the APOLLO Consortium's Community Advisory Council, will aid in integrating genetic and nongenetic risk factors to improve health outcomes. Moving forward, research efforts must focus on elucidating APOL1-associated disease mechanisms, refining risk stratification, and developing targeted therapeutics. Implementing innovative communication strategies, including culturally competent counseling, digital education tools, and standardized decision aids, will be vital in making genetic information both accessible and actionable. By addressing these challenges, the medical community can fully leverage genetic testing to advance personalized medicine, improve patient outcomes, and reduce disparities in kidney disease care.
