摘要: 用扩增片段长度多态性技术(Amp-FLP)分析中国人的D5S436位点的DNA多态性。检测了92名无血缘关系的中国人,发现了8个等位基因,22种基因型,杂合性为78.26%,多态信息量为0.79.观察的基因型频率的分布符合Hardy-Weinberg遗传平衡。检测的4例哮喘家系成员的基因型结果说明该位点属孟德尔式遗传,并可以作为中国人的哮喘基因的遗传标记对哮喘家系进行基因诊断.

Abstract: To detect the polymorphsism of D5S436 locus by using amplified fragment length polymorphism(Amp-FLP), allele and genotype frequencies of the hightly polymorphic D5S436 locus were determined in 92 unrelated Chinese individuals. The amplified fragments were separated by denaturing polyacrylamide gel electrophoresis and the gel was silver stained. 8 alleles and 22 genotypes were observed in this population. The heterozygosity was 78.26%. The polymorphism information content(PIC)is 0.79. Amp-FLP genotyping linkage analyses were carried out in four asthma families, demonstrated that the locus was inherited according to Mendelian law and have a clear result. It is concluded that D5S436 can be used as a genetic marker of asthma in Chinese and maybe helpful in the gene diagnosis of asthma.

Key words: D5S436 locus, DNA polymorphism, asthma
