Linear deposition of IgA immunoglobulin was found along the glomerular basement membrane in two patients with normal renal function and no pulmonary abnormalities. One patient had recurrent gross hematuria and a mild focal proliferative glomerulonephritis without deposits on electron microscopy; the second patient had a renal cell carcinoma. This observation of linear IgA antibody deposition in the absence of Goodpasture's syndrome or diabetes mellitus extends the spectrum of diseases associated with glomerular basement membrane-IgA deposition.
