Proteinuria, even in healthy individuals, is an indicator of renal dysfunction, and the type of the excreted protein fraction (albumin, low molecular weight proteins (LMW) or high molecular weight proteins (HMW)) may be a marker of the type of kidney disease, e.g., albumin and higher molecular mass protein excretion may indicate glomerular damage, while loss of LMW proteins may indicate tubular diseases [6]. This evidence concerns the gene ALB and kidney disorder.
