A normal serum albumin level at diagnosis of FSGS recurrence (point estimate 6.46, 95% CI 1.55–26.84, P  value = 0.01) and lower age at transplant (point estimate 0.92, 95% CI 0.85–0.98, P  value = 0.014) were the significant predictors. This evidence concerns the gene ALB and focal segmental glomerulosclerosis.
