    Abstract

    A 64-year-old man was admitted to our hospital because of possible liver cirrhosis. His serum cholinesterase was anomalously low with a delta pH of 0.1 (normal range; 0.8-1.1). His enzyme was more heat-labile than the normal controls. Km value of his enzyme for benzoylcholine was 1.1 x 10(-5) mol/l, while that for normal controls was 2.3 x 10(-6) mol/l. In addition, isozymic alteration of his enzyme was observed. Sequencing of the white blood cell DNA of the patient showed a point mutation at nucleotide 1093 (GGA to CGA), which changes codon 365 from glycine to arginine.
