homeostasis/metabolism
• adults develop progressive proteinuria with massive albuminuria at 40 months of age
• massive albuminuria is seen at 40 months of age, about 60-fold higher than in controls
• however, serum albumin is not different

renal/urinary system
• adults develop progressive proteinuria with massive albuminuria at 40 months of age
• massive albuminuria is seen at 40 months of age, about 60-fold higher than in controls
• however, serum albumin is not different
• adults show collapsed F-actin in podocytes
• cell junctions of effaced foot processes resemble tight junctions
• adults show widespread foot process effacement
• newborns exhibit persistence of cuboidal podocytes, wide foot processes and tight-junction-like cell junctions in lieu of slit-diaphragms
• slit-diaphragms are decreased in adults
• adults show microvillar transformation
• adults exhibit focal segmental glomerulosclerosis, with the presence of protein casts and tubulointerstitial nephropathy
