Abstract
BACKGROUND Tandem repeats (STRs) are genomic markers of particular interest in forensic and population genetics. Most of the population data currently available correspond to the variation of STRs of forensic panels, which barely include dinucleotide tandem repeats. AIMS The aim of the study is to test the usefulness of a battery of dinucleotide STRs on the X chromosome for population and forensic studies. SUBJECTS AND METHODS A total of 672 individuals from 12 Mediterranean populations and two external references were analysed for 15 X-STR following the instructions of the commercial company and using control DNA from the CEPH centre whose sequences are published in GenBank. Genotypic results were analysed using standard population genetics methods including estimates of linkage disequilibrium, population structure and gene flow. Common forensic efficiency parameters were calculated. RESULTS The analysed X-STRs show high values of genetic diversity, comparable to other STRs of more common use. No significant associations between markers were found. A slight population structure was detected between the two shores of the Mediterranean. The X-STRs studied here present a similar degree of variability to that of other X-STRs used in forensics. CONCLUSION Tandem-repeated dinucleotides are a good tool for evidencing population differences here. Forensic parameters indicate that the dinucleotide X-STRs are suitable for forensic use.

A genetic overview of Atlantic coastal populations from Europe and North-West Africa based on a 17 X-STR panel. Forensic Sci Int Genet 2016; 27:167-171.

Abstract
The forensic use of X-STRs requires the creation of allele and haplotype frequency databases in the populations where they are going to be used. Recently, an updated Spanish allele and haplotype frequency database for the new 17 X-STR panel has been created, being the only database available up to now for this new multiplex. In order to broaden the forensic applicability of the 17 X-STR panel, 513 individuals from four different populations located on the Atlantic Coast of Europe and North-West Africa have been studied, i.e. Brittany (France), Ireland, northern Portugal, and Casablanca (Morocco). Allele and haplotype frequency databases, as well as parameters of forensic interest for these populations are presented. The obtained results showed that the 17 X-STR panel constitutes a highly discriminative tool for forensic identification and kinship testing in the studied populations. Furthermore, we aimed to study if these populations located on the Atlantic coast actually share alike allele and haplotype frequency distributions since they have experienced genetic exchanges throughout history. This would allow creating larger forensic databases that include several genetically similar populations for its use in forensic casework. For this purpose, pairwise FST genetic distances between the analyzed populations and others from the Atlantic Coast previously studied with the 17 X-STR panel or the ten coincident markers included in the decaplex of the GHEP-ISFG were estimated. Our results suggest that certain nearby populations located on the European Atlantic coast could have underwent episodes of genetic interchange as they have not shown statistically significant differentiation between them. However, the population of Casablanca showed significant differentiation with the majority of the European populations. Likewise, the autochthonous Basque Country and Brittany populations have shown distinctive allele frequency distributions between them. Therefore, these findings seem to support that the use of independent allele and haplotype frequency databases for each population instead of a global database would be more appropriate for forensic purposes.
