This study estimated short tandem repeat (STR) allele frequencies in North Portugal using the AmpFlSTR Profiler Plus kit. These frequencies are crucial for forensic DNA profiling and population genetics research.

Area of Science:

  • Forensic Genetics
  • Population Genetics
  • Human Genetics

Background:

  • Short tandem repeats (STRs) are highly variable regions of DNA used in forensic identification.
  • Accurate population-specific allele frequency data is essential for the reliable interpretation of DNA evidence.
  • The AmpFlSTR Profiler Plus kit is a standard tool for forensic DNA analysis.

Purpose of the Study:

  • To determine the allele frequencies for nine specific STR loci in a North Portuguese population.
  • To provide a foundational dataset for forensic casework and population genetics studies in the region.
  • To contribute to the global database of STR allele frequencies.

Main Methods:

  • Genotyping of nine STR loci (D3S1358, VWA, FGA, D8S1179, D21S11, D18S51, D5S818, D13S317, D7S820) using the AmpFlSTR Profiler Plus kit.

  • Analysis of DNA samples from 365-427 unrelated individuals residing in North Portugal.
  • Estimation of allele frequencies for each STR locus.

    • Main Results:

    • Allele frequency distributions were calculated for all nine STR loci in the North Portuguese sample.
    • The data provides a detailed genetic profile of the studied population.
    • Observed frequencies can be compared with other populations to understand genetic diversity.

    Conclusions:

    • The generated STR allele frequency data is valuable for forensic DNA analysis in North Portugal.
    • This study enhances the accuracy of DNA profile interpretation in legal investigations.
    • The findings support the use of the AmpFlSTR Profiler Plus kit for population-specific forensic applications.
