Answer

Glomerulopathy with fibronectin deposits

GFND is a genetically heterogeneous autosomal dominant disorder which manifests as proteinuria, hypertension, type IV renal tubular acidosis. It eventually leads to end-stage renal failure, in the second to fifth decade of life. Type 1 GFND maps to chromosome 1q32, but the gene is unknown at this time. Type 2 GFND is caused by mutations in the FN1 gene located on chromosome 2q34.
