APOL1 and kidney failure: Saraf et al. reported that this risk allele was associated with a lower eGFR (beta −11.7, p = 0.002), worse CKD stage (OR 3, p = 0.00013), and higher risk of kidney failure (OR 10, p = 0.00032) in adult patients from the UIC cohort after adjusting for APOL1 variants, but not in the Walk-PHaSST cohort [26].
