CMIP upregulation has been described in renal biopsies from patients with idiopathic MCNS, FSGS and membranous nephropathy, whereas CMIP is not generally expressed in inflammatory and proliferative glomerular diseases, such as IgA nephropathy or active lupus nephritis [6, 26, 27]. The gene discussed is CMIP; the disease is IgA glomerulonephritis.
