Population genetic data for 17 STR markers from Lebanon

Area of Science:

• Population Genetics
• Forensic Science
• Human Identification

Background:

• Autosomal short tandem repeats (STRs) are crucial markers in forensic science and human identification.
• Understanding STR allele frequencies within specific populations is essential for accurate forensic analysis and database development.
• Previous data on STR profiles in the Lebanese population was limited, necessitating comprehensive population genetic studies.

Purpose of the Study:

• To characterize the genetic variation of seventeen autosomal STR loci in the Lebanese population.
• To evaluate the forensic suitability of these STR loci for individual identification and paternity testing.
• To compare allele frequency data with neighboring populations to assess genetic relatedness and population structure.

Main Methods:

• Genotyping of 192 individuals using the Promega PowerPlex 16 STR kit (15 loci).
• Genotyping of 275 individuals using Applied Biosystems AmpFlSTR Identifiler and SGM+STR kits.
• Analysis of allele frequencies and calculation of forensic and population genetic parameters for 17 STR loci.

Main Results:

• No significant differences in allele frequencies were observed for the shared CODIS 13 loci across the tested STR kits within the Lebanese population.
• Population and forensic genetic parameters were calculated for all 17 analyzed STR loci.
• Comparison with allele frequencies from geographically proximate populations provided insights into regional genetic patterns.

Conclusions:

• The analyzed autosomal STR loci are suitable for forensic applications in the Lebanese population.
• The genetic data generated contributes to the global understanding of human population structure and STR diversity.
• This study provides valuable genetic information for forensic casework and anthropological research within the region.
