title: Population data of the AmpFlSTR® NGM™ loci in South Portuguese population.
abstract: Allele frequencies and other relevant forensic parameters for 15 loci studied with AmpFlSTR(R) NGM™ kit were calculated in a population of individuals residing in the south of Portugal. Blood stain samples were obtained from a total of 452 unrelated individuals involved in paternity testing casework. The kit has five loci - D10S1248, D22S1045, D2S441, D1S1656 and D12S391 not present in any other kit used in our laboratory (Powerplex 16 System and Identifiler Plus). In our laboratory, this new kit is used as a screening tool to solve deficient cases as fatherless paternity test, and to help in paternity investigations with only one genetic incompatibility after the use of routine seventeen loci. Furthermore, this five loci included in the European Standard Set are also recommended by the European Network of Forensic Science Institutes "ENFSI" and the European DNA Profiling group "EDNAP". These studies are necessary to calculate statistical forensic parameters such as power of discrimination, power of exclusion, minimum allele frequency. Statistical parameters such as heterozigoty, homozigoty and combined power of exclusion were determinated. This kind of study is part of the Quality Program for Certificated Forensic Laboratories.
