Figure 3: Light and electron microscopy findings of Patient 7 diagnosed with minor glomerular abnormalities by light microscopy (Table 1). (A) Note the lack of mesangial matrix expansion and absence of any abnormality in the capillary wall. (B) Electron microscopy showing diffuse thickening of the glomerular basement membrane (around 600 nm), which is associated with the effacement of podocytes of foot processes. (A): PAS staining; original magnification: 200×.
