Fibronectin Glomerulopathy Caused by the Y973C Mutation in Fibronectin: A Case Report and Literature Review.

Fibronectin glomerulopathy is a rare autosomal dominant inherited glomerular disease associated with massive deposition of fibronectin. We recently diagnosed fibronectin glomerulopathy in a 29-year-old woman presenting nephrotic syndrome. Genetic analysis of fibronectin 1 gene showed heterozygosity for the Y973C mutation. However, this mutation was not found in her parents. She had stable renal function but persistent nephrotic proteinuria after one-year follow-up.
