摘要: 为了揭示中国汉族人5-HT2a受体基因T102C多态性基因频率的分布,我们随机抽取了226例汉族健康人作研究,用限制性片段长度多态性(RFLPs)技术测定研究对象的基因型和等位基因。结果发现汉族正常人5-HT2a受体基因T102C多态性基因型频率依次为:A1/A2=0.5044,A1/A1=0.2965,A2/A2 =0.1991,两种等位基因频率依次为:A1=0.5487,A2=0.4513,杂合度H=0.50 44、期望杂合度h=0.4953,多态信息量PIC=0.3726,表明T102C多态性具有合适信息,对疾病的关联研究,法医学鉴定有一定的价值。
Abstract:To investigate the distribution about genotype and allele frequencies of T102C polymorphism in the 5-HT2a receptor gene Chinese Han population,the genotypes and alleles of 226 healthy person were examined with Restriction Fragment Length Polymorphisms(RFLPs)technique.The genotype frequencies are as follows:A1/A2=0.5044,A1/A1=0.2965,A2/A2=0.1991,respectively,and the allele frequencies are as follows:A1=0.5487,A2=0.4513,respectively.The heterozygosity(H)is 0.5044,the expected heterozygosity(h)is 0.4953,and the Polymorphism Information Content(PIC)is 0.3726.Our findings suggest that the T102C polymorphism in 5-HT2a receptor gene may have suitable information to be used for association study or forensic identification.
