Abstract
Apolipoprotein L1 (APOL1) high-risk genotypes strongly associate with HIV-associated nephropathy, and antiretroviral therapy reduces the incidence of HIV-associated nephropathy and progression to end-stage kidney disease. Wudil et al. report cross-sectional APOL1 associations with proteinuria and estimated glomerular filtration rate in a northern Nigerian sample with HIV infection on antiretroviral therapy. Multiple ethnic groups with different APOL1 risk variant frequencies were included. Overall, APOL1 was associated with proteinuric chronic kidney disease; however, relationships with underlying causes of nephropathy and progression rates require further study.
