Area of Science:

  • Forensic genetics
  • Population genetics
  • Molecular biology

Background:

  • Accurate forensic DNA profiling relies on population-specific allele frequency databases.
  • Limited genetic data exists for Mozambican populations, hindering forensic casework.
  • Short Tandem Repeat (STR) markers are crucial for human identification.

Purpose of the Study:

  • To estimate allele frequencies for twelve STR loci in a Mozambican population sample.
  • To provide foundational genetic data for forensic applications in Mozambique.
  • To evaluate the utility of AmpFlSTR Profiler Plus and GenePrint CTTv kits in this region.

Main Methods:

  • DNA samples were collected from 110 unrelated individuals residing in Mozambique.
  • Allele frequencies were determined for STR loci using the AmpFlSTR Profiler Plus and GenePrint CTTv kits.

  • Statistical analysis was performed to estimate allele frequencies for each locus.

    • Main Results:

    • Allele frequency distributions were calculated for D3S1358, VWA, FGA, D8S1179, D21S11, D18S51, D5S818, D13S317, D7S820, TH01, TPO, and CSF1PO.
    • The data provides a baseline for genetic variation within this Mozambican cohort.
    • Observed heterozygosity and polymorphism information content were implicitly determined.

    Conclusions:

    • The generated allele frequency data is vital for the interpretation of forensic DNA profiles in Mozambique.
    • This study contributes to the development of a national DNA database for improved forensic investigations.
    • The findings support the use of the AmpFlSTR Profiler Plus and GenePrint CTTv kits for Mozambican populations.
