国人布-加综合征与FⅤ Leiden突变的相关研究

Study on Relationship Between Chinese Budd Chiari Syndrome and Factor Ⅴ Leiden Mutation

目的 :探讨国人布 -加综合征 (BCS)与凝血第 因子 L eiden(F L)突变的相关性。方法 :收集 2 9例国人BCS(其中 2 5例为散发 BCS、4例为家族性 BCS)和 2 9名健康对照者 ,并对其血样进行 PCR- RFL P的 F L 突变分析。结果 :2 9例 BCS中 ,共有 3例 F L 突变阳性 ,均为家族性 BCS病例。其中家系 A姐妹均有 F L 突变 ,家系 B妹妹突变阳性 ,均为杂合性突变。散发病例无 1例阳性。对照组无 1例阳性。 2 9例国人 BCS中 ,F L 突变频率为0 .0 5 17,而 4例家族性 BCS的 F L 突变频率则为 0 .375 0。2 9例 BCS病例组与 2 9例对照组间 F L 突变频率无统计学差别 ,但家族性 BCS病例组与对照组间 F L 突变频率有显著统计学差别。结论 :国人家族性 BCS与 F L 突变相关 ,国人散发性 BCS与 F L

Objective:Our aim was to study the relationship between factor v Leiden (FⅤL) mutation and Chinese Budd Chiari syndrome (BCS). Methods:Twenty nine BCS patients (25 patients with sporadic BCS,4 with familial BCS ),29 healthy persons were detected for FⅤL mutation with PCR RFLP.Results: FⅤL mutation was detected in 3 of 4 patients with familial BCS. Two patients in A family and one patient in B family had FⅤL mutation. The mutation was heterozygous. The mutation frequency was 0.0517 in 29 pationts with BCS, 0.3750 in 4 with familial BCS.The frequency of FⅤL mutation in patients and healthy persons showed no statistical difference,but frequency of FⅤL mutation between patients with familial BCS and healthy persons showed significant difference.Conclusion:The FⅤL mutation was related to Chinese familial BCS, but not related to Chinese BCS.
