Clinical feature: 

Definition: Microcoria-congenital nephrotic syndrome is an autosomal recessive disorder caused by mutations of laminin beta-2, an essential component of mature glomerular laminin located in the glomerular basement membrane. The clinical course is characterized by severe proteinuria and early death.
