Glomerulopathy with fibronectin deposits is a genetically heterogeneous autosomal dominant disorder characterized clinically by proteinuria, microscopic hematuria, and hypertension that leads to end-stage renal failure in the second to fifth decade of life. Pathologic examination shows enlarged glomeruli with mesangial and subendothelial fibrillary deposits that show strong immunoreactivity to fibronectin (Castelletti et al., 2008).
