Correlation of osteoprotegerin gene polymorphisms G1181C and osteoprotegerin serum levels with the presence of acute coronary syndrome

Objective To investigate the association between the single nucleotide polymorphisms （SNPs）, G1181C of osteoprotegerin （OPG） gene and its serum levels with the presence of Acute Coronary Syndrome（ACS）. Methods We investigated 134 Chinese Han patients in Shanghai. The patients were divided into two groups by the presence of ACS and coronary angiography ： 69 with ACS and 65 control group （without CA＇D）. The serum concentrations of OPG were determined by ELISA. The genomic DNA was extracted using die- lectric purification assay. The gene fractions in which the mutations located were selectively amplified from genomic DNA samples using a multiplex polymerase chain reaction （ PCR）, followed by multiplex ligase detection reaction （LDR）. The fluorescence level of LDR-PCR products was detected by DNA sequencer. Results There was no significant diference in frequencies of genotype and allele in polymor- phisms GI 181C between patients with ACS and control group. Conclusion The G1181C polymorphisms of OPG and its serum levels are not associated with the presence of ACS. The C allele might be the pathogenic factor of ACS.
