The analysis of allelic deletion in 4 cases of Amelogenin loci in paternity testing / 复旦学报（医学版）

Objective To apply PowerPlex(R) 21 System Kit and AGCU 21 + 1 STR Fluorescence Detection Kit as supplementary detection kit in some samples with Amelogenin locus X deletion.Methods While with the help of Investigator Argus X-12 Kit,MicroreaderTM 19X ID System kit and the application of capillary electrophoresis,the complete X pattern of these four samples can be identified.Results From Mar,2013 to Dec,2016,4 cases of male samples with Amelogenin locus X deletion have been found.Conclusions Sometimes Amelogenin locus X deletion may happen when using PowerPlex(R)21 System Kit and AGCU 21 + 1 STR Fluorescence Detection Kit,while validating with other forensic biology detection kit can assure the accuracy of genotyping.
