Ultrastructural defects of the glomerular basement membranes associated with primary glomerular nephropathies.

abstract：:Electron microscopy defined classic patterns of hereditary glomerular disease long before genetics revealed an underlying specific mutation. Genetic analysis is now easier to perform in clinical practice but an earlier optimism that genetics would predict disease severity and phenotype is challenged. The classic parad...
