Pseudo-Hypertriglyceridämie bei Glycerokinase-Mangel

Falsely high serum triglyceride concentrations (410-850 mg/dl) were measured in four members of a family of five from Franconia in Germany. The cause was hyperglyceridaemia on the basis of glycerol kinase deficiency. None had any symptoms and no other metabolic anomaly was demonstrated. The possibility of glycerol kinase deficiency should be considered in any case of elevated serum triglyceride concentration but with clear serum, normal lipid electrophoresis and lack of response to lipid-lowering measures.
