Description : Focal segmental glomerulosclerosis (FSGS) is a pathologic entity associated clinically
with proteinuria, the nephrotic syndrome (NPHS), and progressive loss of renal function.
It is a common cause of end-stage renal disease (ESRD) (Meyrier, 2005). For a general
phenotypic description and a discussion of genetic heterogeneity of focal segmental
glomerulosclerosis and nephrotic syndrome, see FSGS1 (603278).;
