Genetic analysis of two STR loci (VWA and TPOX) in the Iranian province of Khuzestan.

ABSTRACT: OBJECTIVES:Short tandem repeat (STR) loci are the most informative DNA genetic markers for attempting to individualize biological material for application in paternity and forensic cases. MATERIALS AND METHODS:Blood samples were collected and the total genomic DNA was extracted. The DNA samples were used for genotyping VWA and TPOX STR loci using PCR and polyacrylamide gel electrophoresis. RESULTS:This report presents allele frequency data and parameters of biological or legal interest, such as heterozygosity value, polymorphic information content (PIC), genetic diversity index (GD) and population parameter (?) in Arab and non-Arab population of Khuzestan province (Iran) for the loci VWA and TPOX. Blood samples (N= 392 for VWA and N=308 for TPOX) were collected from individuals unrelated throughout Khuzestan province. The loci were genotyped using the polymerase chain reaction (PCR) followed by polyacrylamide gel electrophoresis (PAGE) and silver staining. Chi-square test showed that neither STR loci were in agreement with the Hardy-Weinberg equilibrium. CONCLUSION:The examined STR loci in this study have proven a relatively high genetic variation in the Iranian population. The data could be used for construction of a forensic genetic database for the Iranian population.
