This study investigated the prevalence of Tyr204Phe and Val34Leu polymorphisms in two Brazilian ethnic groups (171 Caucasians and 27 Blacks, and 117 men and 81 women) and in patients with recurrent miscarriages (RM) (...This study investigated the prevalence of Tyr204Phe and Val34Leu polymorphisms in two Brazilian ethnic groups (171 Caucasians and 27 Blacks, and 117 men and 81 women) and in patients with recurrent miscarriages (RM) (86 women: 53 Caucasians and 33 Blacks). Study groups were matched to control groups by race and age. The prevalence of these polymorphisms did not differ between patients with RM and controls or between Caucasian and blacks, suggesting that these polymorphisms cannot be considered a risk factor for RM.展开更多
目的:研究海南地区汉族人群、黎族人群、脑梗死患者、冠心病患者FⅧ val 34Leu分布特点。方法:用聚合酶链反应、限制性片段长度多态性分析及核苷酸顺序测定检测205名汉族正常人、236名黎族正常人、196例脑梗死患者、188例冠心病患者(心...目的:研究海南地区汉族人群、黎族人群、脑梗死患者、冠心病患者FⅧ val 34Leu分布特点。方法:用聚合酶链反应、限制性片段长度多态性分析及核苷酸顺序测定检测205名汉族正常人、236名黎族正常人、196例脑梗死患者、188例冠心病患者(心肌梗死/非心肌梗死,55/133)FⅩⅢA链 Val 34 Leu多态性。结果:汉族人群、黎族人群、脑梗死组未发现Val 34 Leu多态性,在冠心病组中发现1例Val 34 Leu杂合子。结论:FⅧ Val 34 Leu变异在中国人群中不是多态性,与缺血性心脑血管疾病没有关联,不是中国人群中防止动脉血栓性疾病的保护性因素。展开更多
