VNTR遗传标记的亲权鉴定研究

PATERNITY TESTING BY ANALYSIS OF THREE VNTR GENETIC MARKERS

采用Amp－FLP技术研究人类血液、组织VNTR位点D1S80（pMCT118）、D17S30（pCNZ－22）和ApoB3’位点的遗传多态性，并应用于亲权鉴定案件，获得满意结果。D1S80、D17S30和ApoB3’的DP值分别为0．962、0．956和0．960，累积父权排除率（EPP）为94．51％，远远高于传统血型的DP值和EPP值，是亲权鉴定和个体识别有效方法。

The polymorphisms of VNTR loci D1S80 (pMCT 118), D17S30 (pYNZ-22 ) and ApoB3' in blood and tissues were detected by amplified fragment length polymorphism (Amp-FLP) technique,and was applied in the paternity testing cases. The discriminating power (DP) of D1S80,D17S30 and ApoB3'were 0. 962, 0. 956 and 0. 960 respectively. The cumulative probability of paternity exclusion (EPP) of the three VNTR loci was 94. 51 %,higher than that of conventional blood typings.
