[英文释义] Heat- and storage-labile plasma glycoprotein which accelerates the conversion of prothrombin to thrombin in blood coagulation. Factor V accomplishes this by forming a complex with factor Xa,phospholipid,and calcium (prothrombinase complex). Deficiency of factor V leads to Owren's disease.

Our results showed as follows : 1 ) the spl and rsal polymorphisms of the collagen type 1 alpha 1 ( col1 al ) gene, the-174g / c promoter polymorphism of the interleukin-6 ( il-6 ) gene, the asn363ser polymorphism of the glucocorticoid receptor ( gr ) gene, and the t ? c polymorphism in intron 5 of the transforming growth factor pi ( tgf-p ! ) gene are absent or too rare in chinese . compared the polymorphisms of these five markers with other populations using % 2 test and fisher's exact two-tailed test, significant differences of allele and genotype frequency distributions were observed at these polymorphisms ( p < 0.001 ) 结果表明:1)白介素6(il?6)基因的?174gc多态性、型胶原蛋白_1(col1a1)基因的sp1和rsa多态性、转化生长因子_(tgf-_1)基因的内含子5tc多态性和糖皮质激素受体(gr)基因的asn363ser的多态性在中国人群中均未发现或者多态性很低;x~2检测和fisher精确(双尾)检验比较这些多态性的频率,发现在中国人群与其它种群或人群中,等位基因和基因型存在显著的差异(p0.001)。
