[Correlation between osteoprotegerin gene 209G/A, 245T/G and 1181G/C polymorphism and acute coronary syndromes in Han people of Fujian area].

OBJECTIVE

To explore the association of osteoprotegerin (OPG) gene polymorphisms 209G/A, 245T/G and 1181G/C in the Han population of Fujian province with acute coronary syndrome (ACS) and its severity.

METHODS

A prospective study was conducted. Two hundred and fifty-two cases without sibship of Fujian Han people was enrolled from July 2010 to September 2011, in which 68 healthy subjects as controls. One hundred and eighty-four patients with ACS were divided into three groups, 60 had one-vessel, 68 had two-vessel, and 54 had three-vessel lesion, 2 had not been found stenosis. DNA was extracted from venous blood, different groups of OPG gene polymorphism was identified by Sanger Method. OPG 209G/A, 245T/G and 1181G/C genotype frequencies and allelic frequencies were analyzed between ACS subjects and normal subjects and among the three groups of ACS, and the relationship between gene polymorphisms and ACS severity.

RESULTS

No significant differences were observed in the genotype and allelic frequencies of OPG gene 209G/A, 245T/G between the ACS and control groups. Significant differences were observed in the genotype and allelic frequencies of OPG gene 1181G/C between the ACS and control groups [1181G/C GG: 92 (50.0%) vs. 43 (63.2%), CC: 26 (14.1%) vs. 0, GC: 66 (35.9%) vs. 25 (36.8%), χ(2)=11.240, P=0.004; allelic gene G: 250 (67.9%) vs. 111 (81.6%), allelic gene C: 118 (32.1%) vs. 25 (18.4%), χ(2)=9.148, P=0.002]. No significant differences were observed in the genotype and allelic frequencies of OPG gene 209G/A, 245T/G and 1181G/C between those groups.

CONCLUSIONS

There were no significant difference in frequencies OPG genotype and allele in polymorphisms 209G/A, 245T/C between patients with ACS and control group in Han population of Fujian province. There were difference in frequencies OPG genotype and allele in polymorphisms 1181G/C between patients with ACS and control group, but it was not differently distributed among patients with single-, double-, or triple-vessel lesion.
