Additionally, FAS was recently reported to predict eGFR calculated by the creatinine/cystatin C-based CKD-EPI equation with a median bias 10.2 mL/min/1.73 m2 (95%CI = 9.2–10.9) in a population of 1913 Chinese CKD patients aged 50.3 ± 18.2 years [29]. The gene discussed is CST3; the disease is chronic kidney disease.
