摘要： 亲子鉴定中常会发生STR(short tandem repeats,短串联重复)突变的情况。突变对亲子关系的判定会造成困扰。对STR突变规律和亲子鉴定中所遇到的STR突变问题、突变的判定、突变下非父排除率和父权指数的计算以及需与突变区分的情形等问题进行综述和讨论。

关键词: 亲子鉴定, 短串联重复, 突变

Abstract: STR(short tandem repeats) mutations are encountered frequently in paternity casework because STR has relatively high mutation rate.Dealing with possible mutations in paternity cases is a difficult task.This paper reviews the characteristics of STR mutation and the problems related with STR mutation.Issues, such as determination of mutation, calculation of paternity index and probability of exclusion and distinction between mutation and its similarity, are discussed.

Key words: mutation, short tandem repeats(STR), paternity testing
