  • High-risk genotype is defined as carrying two APOL1 renal risk alleles, and low-risk genotype is defined as carrying one or zero APOL1 renal risk alleles. Data are presented as mean±SD. To convert serum creatinine from milligrams per deciliter to micromoles per liter, multiply by 88.4. Family history of hypertension and ESRD was defined as first degree relative with these conditions.
