Haplotypes for 13 Y-chromosomal STR loci in South Tunisian population (Sfax region)

Nine Y-STR loci from the minimal haplotype (DYS19, DYS385a/b, DYS3891, DYS38911, DYS390, DYS391, DYS392, DYS393) included in Y-STR Haplotype Reference Databases (YHRD) with 4 additional Y-STRs (DYS436, DYS437, DYS438, DYS439) were analyzed by PCR using duplex and Y-PLEX (TM) 12 kit, followed by automatic genotyping in a sample of 105 Tunisian males originating from Sfax region (south Tunisia). Allelic frequencies and gene diversities for each Y-STR locus were determined. The high haplotype diversity (0.9932) and discrimination capacity (0.7714) show the usefulness of these loci for human identification in forensic studies and paternity tests in Tunisia. The most common haplotype was shared by 4.7% (5 individuals) of the sample was only found in samples from the Tunisian population reported in YHRD. One private allele for DYS392 (allele 17) was discovered and duplications were observed for five loci (DYS19, DYS3891, DYS393, DYS437 and DYS439). (c) 2005 Elsevier Ireland Ltd. All rights reserved.
