OBJECTIVETo investigate the T13254C polymorphism frequency in GPVI gene among Chinese Han population and its relevance to the arterial thrombotic diseases.

METHODSThe enrolled population in this study consisted of 314 healthy subjects and 274 patients with myocardial or cerebral infarctions. GPVI T13254C genotypes were determined by PCR amplification of a 355 bp fragment encompassing exon 5 of GPVI gene, followed by Msp I digestion of the product. The digested products were analyzed in 15% polyacrylamide gel electrophoresis (PAGE).

RESULTSThe frequencies of the T allele and C allele in the T13254C polymorphism were 0.9809 and 0.0191, respectively, with a frequency of heterozygous of 0.0319, which were significantly different from those reported in western population (P < 0.01). As compared with controls, no significant difference in T13254C genotype distribution was found in the arterial thrombotic diseases group.

CONCLUSIONThe GPVI T13254C polymorphism appears in a low frequency in Chinese Han population. No relationship is found between T13254C polymorphism and the risk for thrombotic diseases.
