A population study on 10 tetrameric STR loci (ACTBP2 (=SE33), D18S51, D8S1132, D12S391, D2S1360, D3S1744, D5S2500, D7S1517, D10S2325, D21S2055) was performed with Germans from Bavaria.     

Allele frequencies of six miniSTR loci (D10S1248, D14S1434, D22S1045, D4S2364, D2S441 and D1S1677) in a Spanish population

Allele frequencies and forensic parameters for six miniSTR autosomal loci (D10S1248, D14S1434, D22S1045, D4S2364, D2S441 and D1S1677) were obtained from a sample of 264 unrelated individuals from Spain. No significant deviations from Hardy-Weinberg expectations were found. Due to the small PCR products (<125 bp), the use of these non-CODIS (NC) miniSTRs can increase the probability that a degraded sample can be typed. Additionally, these systems can be used in routine paternity analyses where more markers are needed to increase the power of exclusion or in complex paternity cases (e.g. involving closely related individuals).

Genetic variation of 15 STR loci (D3S1358, vWA, FGA, TH01, TPOX, CSF1PO, D5S818, D13S317, D7S820, D16S539, D2S1338, D8S1179, D21S11, D18S51, and D19S433) in populations of north and central Poland

Allele frequencies for 15 short tandem repeats (STRs) included in AmpFlSTR Profiler and AmpFlSTR SGM Plus kits were obtained from populations of Pomorze Gdanskie, Wielkopolska, Kujawy, Pomorze Zachodnie, Mazury and Mazowsze regions of Poland.     

Allele frequencies for nine STR loci (D3S1358, vWA, FGA, D8S1179, D21S11, D18S51, D5S818, D13S317, D7S820) in the Italian population

Genotype and allele frequencies for STR loci D3S1358, vWA, FGA, D8S1179, D21S11, D18S51, D5S818, D13S317, D7S820 were investigated in 289 unrelated Italian Caucasian individuals from the North and South regions. After co-amplification by polymerase chain reaction, automatic DNA profiling of these nine STR loci was performed by ABI PRISM((R)) 310 DNA Genetic Analyzer. For each locus, statistical parameters for forensic and paternity purposes were then calculated; the combined power of discrimination and the combined power of exclusion of all nine loci were 0.9999999999917 and 0.99992 for the Northern population and 0.9999999999921 and 0.99991 for the Southern population.     

Population genetic studies on the tetrameric short tandem repeat loci D3S1358, VWA, FGA, D8S1179, D21S11, D18S51, D5S818, D13S317 and D7S820 in Egypt.

The short tandem repeat loci (STRs) D3S1358, VWA, FGA, D8S1179, D21S11, D18S51, D5S818, D13S317, D7S820 and a locus allowing for sex-discrimination (amelogenin) can be co-amplified by the polymerase chain reaction using a commercially available kit (AmpFlSTR Profiler plus, Perkin-Elmer Biosystems, San Jose, CA) and subsequently typed using capillary electrophoresis (ABI Prism 310 Genetic analyzer, Perkin Elmer Applied Biosystems, San Jose CA). To establish databases for these loci for an Arab population sample from Egypt, 140 unrelated persons were typed. Analysis of these data revealed that all loci except for VWA were in Hardy-Weinberg equilibrium, that the combined mean paternity exclusion chance (MEC) was 0.999875 and that the combined discriminating power (DP) was 2.635 x 10(-11). The allelic distributions found in the Egyptian sample were significantly different at four loci from those found for an Austrian Caucasian population, at all nine loci from an African-American sample and at six of six loci from a Chinese sample. No evidence of linkage equilibrium between any of the co-amplified loci was found. Our results support that the combination of multiplex PCR and capillary electrophoresis can both save time and yield excellent results for paternity testing and stain analysis.
