Population data for 22 autosomal STR loci from Estonia

Area of Science:

• Forensic genetics
• Population genetics
• Human identification

Background:

• Short tandem repeat (STR) loci are essential genetic markers for forensic analysis.
• Accurate population data is critical for interpreting forensic STR profiles.
• Estonian population data for a comprehensive set of STR loci is needed.

Purpose of the Study:

• To determine allele frequencies and population statistics for 22 STR loci in an Estonian population.
• To evaluate the forensic efficacy of these STR loci within the Estonian population.
• To compare findings with existing population data from neighboring regions.

Main Methods:

• Genotyping of 303 unrelated Estonian individuals using three commercial STR amplification kits.
• Analysis of 22 STR loci, including AmpFlSTR(®) Identifiler and PowerPlex(®) systems.
• Statistical analysis of allele frequencies and Hardy-Weinberg equilibrium.

Main Results:

• Allele frequencies for 22 STR loci were established for the Estonian population.
• Most loci showed no significant deviation from Hardy-Weinberg equilibrium, indicating population stability.
• The combined discrimination power for the 22 STR loci in Estonians is exceptionally high (0.9999999999999999999999999877).

Conclusions:

• The analyzed STR loci are highly discriminating and suitable for forensic applications in Estonia.
• The generated population statistics provide a valuable resource for forensic casework in the region.
• This study contributes essential data for accurate DNA profiling and identification in Estonia.
