Résumé

OBJECTIVE@#The study was carried out on the evaluation of number and value of STR loci applied in paternity identification.@*METHODS@#A total of 13 STR loci, divided into four groups, was observed in 102 cases of paternity exclusion and 100 cases of paternity inclusion. PCR amplified products of 13 STR loci were injected into a capillary on the ABI PRISM 310 Genetic Analyzer. GeneScan software analyzed the collected data, which can then be imported into Genotyper software for genotyping of alleles.@*RESULTS@#At least 3 STR loci incompatibilities between alleged father and child were found in all paternity exclusion cases of two observed groups which Cumulative Probability of Exclusion (CPE) was more than 99.99%, and in all paternity inclusion cases of those same observed groups, their Relative Chance of Paternity(RCP) could be over 99.99%.@*CONCLUSION@#The exclusion of paternity should be based on at least three STR loci incompatibilities in the identification practice. As a criterion for evaluation of the number and value of STR loci applied in paternity test, CPE should reach 99.99%.

Résumé

OBJECTIVE@#The study was carried out on application of CODIS loci (FGA, vWA, CSF1PO, TH01, TPOX, D3S1358, D5S818, D7S820, D8S1179, D13S317, D16S539, D18S51 and D21S11) in 100 cases of excluding paternity.@*METHODS@#The PCR amplified products of Profiler Plus and Cofiler amplification kit were injected into a capillary on the ABI PRISM 310 Genetic Analyzer. GeneScan software analyzed the collected data, which can then be imported into Genotyper software for genotyping of alleles.@*RESULTS@#In the group of Mother-Child-Alleged Father, more than 3 STR loci incompatibilities between alleged father and child were found in all observed cases, the mean incompatibility was 6.63; In the group of Alleged Father-Child, 94.0% of all cases observed was found more than 3 STR loci incompatibilities, the mean incompatibility was 5.01.@*CONCLUSION@#The results showed that CODIS loci had good application to excluding paternity, and the choice of hyperpolymorphic markers in investigation, which were valued by DP, H and PE, had direct relation with the augmentation of incompatibilities in excluding paternity.
