Fibronectin glomerulopathy

Familial glomerular nephritis with fibronectin deposits is an autosomal dominant disorder which is characterized by enlarged glomeruli with mesangial and subendothelial fibrillary deposits (fibronectin). The clinical picture includes proteinuria, glomerular hematuria, and hypertension. The glomerular damage eventually leads to end stage renal disease which is reached in the second to fifth decade.

Differentials

Glomerulopathy with fibronectin deposits type 1 is also a genetic disorder whose locus is not yet identified.

Symptoms

Proteinuria
Proteinuria is the first symptom in patients with fibronectin glomerulopathy.
Hematuria
Hematuria is microscopic and glomerular.
Hypertension
Hypertension accelerates with glomerular damage and renal failure.
