Fibrillary glomerulonephritis and Charcot-Marie-Tooth disease

Abstract

We report the case of a young white man with Charcot-Marie-Tooth disease type 1 that began at 4 years. At 15 years, he developed proteinuria, arterial hypertension, and renal insufficiency. Renal biopsy specimens studied by electron microscopy showed deposition of nonamyloidotic microfibrils. This is the first report of fibrillary glomerulopathy associated with this neurological disorder.
