Dogs with membranous glomerulonephropathy had lower serum albumin concentrations (median, 2.1 g/dL; Q1–Q3, 2.0–2.1 g/dL) than dogs with either glomerulosclerosis (median, 3.0 g/dL; Q1–Q3, 2.8–3.3 g/dL; p = 0.01) or other nephropathies (median, 3.0 g/dL; Q1–Q3, 2.6–33.7 g/dL; p = 0.04; Table 1). The gene discussed is ALB; the disease is kidney disorder.
