<unk>  is<unk>  (excessive protein in the urine) caused by renal<unk>  dysfunction. Proteins of low molecular weight are normally filtered at the glomerulus of the kidney and are then normally reabsorbed by the<unk>  cells, so that less than 150 mg per day should appear in the urine. Low-molecular-weight proteins' appearing in larger quantities than this is<unk> , which points to failure of reabsorption by damaged<unk>  cells.<unk>  is a laboratory sign, not a disease; as a sign it appears in various syndromes and diseases, such as Fanconi syndrome.
