等位基因的

As background, about 40% of Alzheimer's patients have at least one copy of the epsilon 4 version of the APOE gene, and the same risk version of the APOE gene is present in about 30% of the general population.

背景资料显示，大约40%的阿尔茨海默病患者至少可检出一个Apo-E ε4等位基因，而相同基因出现的几率在正常人群中约为30%。

Different forms of a gene, which may give rise to different phenotypes, are known as alleles.

不同形式的一种基因，这可能会导致不同的表型，被称为等位基因。

The purpose of the work is to investigate the frequencies and polymorphisms of HIV-1 resistant CCR5delta32,CCR2b-64I,SDF1-3′A alleles in Chinese Dai and Chingpaw populations.Whole blood samples from 101 Dai subjects and 113 Chingpaw were collected randomly and their genomic DNA were extracted with QIAgen Blood Kits.Allelic frequencies were identified by PCR-RFLP analysis.Allelic polymorphisms in Dai population or Chingpaw population and both sexes in the samples were analyzed by χ2 test.

为了调查HIV-1感染相关的等位基因CCR5△32、CCR2b-64I、SDF1-3′A在我国云南省德宏州傣族景颇族人群中的频率和多态性分布，此课题以101例傣族和113例景颇族人群为研究对象，应用PCR、PCR-RFLP(聚合酶链反应-限制性片段长度多态性)分析方法进行检测，计算突变基因频率；并对其群体分布、性别分布进行统计学分析。

Methods HLA-A locus was typed with polymerase chain reaction-sequence specific primer technique for 259 longevous people (aged 90～105) and 214 healthy,randomly sampled subjects (aged 23～70) who live in the same area and comparative analyses were carried out among relevant alleles between the two groups.

The screening method of seven alleles (Z-6,Z-4,Z -2,Z,Z+2,Z+4 and Z+6) in then dinucleotide tandem repeat sequence was st udied. These alleles constitute a microsatellite DNA marker upstream of the tran scription initiation site on the aldose reductase gene.
