Goodpasture syndrome (GPS), also known as anti–glomerular basement membrane disease, is a rare autoimmune disease in which antibodies attack the basement membrane in lungs and kidneys, leading to bleeding from the lungs, glomerulonephritis, [1] and kidney failure. [2]
Thin basement membrane disease (previously referred to as "benign familial hematuria") is, along with IgA nephropathy, the most common cause of hematuria without other symptoms. The only abnormal finding in this disease is a thinning of the basement membrane of the glomeruli in the kidneys.
On electron microscopy, subepithelial deposits that nestle against the glomerular basement membrane seems to be the cause of the thickening. Also, the podocytes lose their foot processes. As the disease progresses, the deposits will eventually be cleared, leaving cavities in the basement membrane.
The glomerular basement membrane of the kidney is the basal lamina layer of the glomerulus.The glomerular endothelial cells, the glomerular basement membrane, and the filtration slits between the podocytes perform the filtration function of the glomerulus, separating the blood in the capillaries from the filtrate that forms in Bowman's capsule.

Membranoproliferative glomerulonephritis (MPGN) is a type of glomerulonephritis caused by deposits in the kidney glomerular mesangium and basement membrane thickening, [2] activating the complement system and damaging the glomeruli. MPGN accounts for approximately 4% of primary renal causes of nephrotic syndrome in children and 7% in adults. [3]
Thin basement membrane disease is an autosomal dominant inherited disease characterized by thin glomerular basement membranes on electron microscopy. It is a benign condition that causes persistent microscopic hematuria. This also may cause proteinuria which is usually mild and overall prognosis is excellent.
Nephritic syndrome is a syndrome comprising signs of nephritis, which is kidney disease involving inflammation. It often occurs in the glomerulus, where it is called glomerulonephritis. Glomerulonephritis is characterized by inflammation and thinning of the glomerular basement membrane and the occurrence of small pores in the podocytes of the ...
Video explanation. Author: Tanner Marshall Editor: Rishi Desai, MD, MPH Membranous glomerulonephritis, also known as membranous nephropathy, is where the glomerular basement membrane, or GBM, which lines the glomeruli in the kidney, becomes inflamed and damaged, which results in increased permeability and proteins being able to filter through into the urine, causing nephrotic syndrome.
