BackgroundAn increased risk of coronary heart disease has been shown to be associated with polymorphisms in PON1 gene in different populations. Polymorphisms in PON2 gene have been associated with the level of plasma lipoproteins and glucose and are thought to play a role in atherosclerosis.MethodsTo detect PONs polymorphisms more rapidly and reliably, we modified and improved the method established by Motti et al. We redesigned the primer for amplifying the common polymorphism at position 311 of PON2, which produced more reliable and efficient amplification.ResultsA second common polymorphism at codon 148 was also detected by our new method, as were the 2 polymorphisms in the PON1 gene. The new method allowed identification of 4 polymorphisms (PON1-192, PON1-55, PON2-148 and PON2-311) simultaneously. The PONs genotypes of 82 healthy persons were identified by this method. The allelic frequencies were: PON1-192: Q 46.3%, R 53.7%; PON1-55: L 95.1%, M 4.9%; PON2-148: A 85.4%, G 14.6%; PON2-311: S 77.4%, and C 22.6%, respectively.ConclusionThis method represents a simple, economical and time-saving technique to simultaneously detect 4 polymorphisms in the PON cluster. It provides a useful application to enable further study of the relationship between PON1 and PON2 and their role in atherosclerosis.
