摘要
目的:探讨南京地区汉族人群中载脂蛋白(a)基因TTTTA五核苷酸重复序列多态性及与血清脂蛋白(a)水平的关系。方法:采用PCR、变性聚丙烯酰胺凝胶电泳和溴乙锭染色等技术分析南京地区156例正常汉人TTTTA五核苷酸重复序列。结果:共检出TTTTA串联次数为5、7、8、9、10和11共6种等位基因和5/9、5/8、7/10、8/8、8/9、8/10、9/9、9/10、9/11、11/11的10种基因型,8等位基因频率在南京地区汉族人群中最高,9及5次之。5等位基因(5/9+5/8)血清脂蛋白(a)水平高于8(8/8)、9(8/9+9/9),但未见有统计学差别。结论:中国汉族南京地区人群存在载脂蛋白(a)基因TTTTA五核苷酸重复序列多态性;未能发现载脂蛋白(a)基因型血清脂蛋白(a)水平的差别。
Objective: To expolre the relation between TTTTA pentanucleotide repeats (PNR) polymorphisms of apolipoprotein(a) [apo(a)] gene and serum lipoprotein(a) in the people of Nanjing area. Methods: The techniques of polymerase chain reaction (PCR) denature polyacrylamide gel electrophoresis and ethidium bromide stain were used to determine the TTTTA PNR polymorphism of apo (a) gene in 156 healthy subjects of Chinese Han people in Nanjing. Results: The Tandem frequency of TTTTA PNR in Nanjingers of Han nationality has 6 alleles of 5、7、8、9、10、11 and 10 genotypes of 5/9、5/8、7/10、8/8、8/9、8/10、9/9、9/10、9/11 and 11/11; the frequency of 8 allele was remarkably higher than 9 and 5. The serum lipoprotein(a) in allele 5(5/9 +5/8) was higher than 8(8/ 8) and 9(8/9 +9/9), but there was no different in statistics. Conclusion:There was polymorphism of TTTTA PNR in people of Han nationality in Nanjing aera; there was no difference in serum lipoprotein(a) among the genotypes of TTTTA PNR polymorphism.
