An international research collaboration led by Queen Mary University of London and the University of the Witwatersrand (Wits) in South Africa has published what researchers are calling the most comprehensive genomic investigation of kidney function ever conducted in African populations. The study, which examines the genetics of chronic kidney disease (CKD) across diverse African populations, represents a significant step toward addressing a longstanding gap in genomic research, which has historically been dominated by data from European ancestry groups.

The findings shed new light on genetic risk factors associated with CKD in African populations and are expected to support future efforts aimed at improving prevention, diagnosis, and treatment of kidney disease — both among African populations and globally.

Chronic kidney disease affects an estimated 850 million people worldwide and is a leading cause of morbidity and mortality. African populations carry a disproportionately high burden of CKD, driven in part by elevated rates of hypertension, diabetes, and genetic predispositions that have been historically understudied.

Researchers indicated the study's findings could have broad implications for global kidney health, given that genetic variants discovered in underrepresented populations often yield novel biological insights applicable across ancestries.
