A Distinctive Pattern of Diversity for the TAS2R38 Gene in North Africa
The TAS2R38 gene is involved in bitter taste perception. This study documents the distinctive diversity patterns in northern Africa of functional single-nucleotide polymorphisms (SNPs) rs713598 and rs1726866 at the TAS2R38 locus and places those patterns in the context of global TAS2R38 diversity. Data previously genotyped with TaqMan assay were analyzed for rs713598 and rs1726866 for 375 unrelated subjects (305 Tunisians from seven locations: Ma…
Genetic analysis of sixteen autosomal STR loci in three Tunisian populations from Makthar, Nabeul and Sousse
Our results strongly supported the application of autosomal genetic markers in anthropological and forensic studies. The analyses conducted at the 15-loci level provide the resolution to assess the phylogenetic relationships among the populations examined and other geographically targeted worldwide populations, while the results resulting from the 10-loci studies provide an understanding of the relationships and origins of the North African popul…

The Orientalisation of North Africa
This study represents an additional step to obtain a comprehensive understanding of the complex demographic history of North African populations
Genetic Susceptibility to Type 2 Diabetes
The present study is the first meta-analysis to evaluate type 2 diabetes (T2D)- associated polymorphisms in cohorts originated from several Tunisian regions. In fact, we evaluated the effect of seven polymorphisms in the following genes—PPARg (Pro12Ala), TNFα (-308A/G), ENPP1(K121Q), TCF7L2(rs7903146°C/T), MTHFR(C677T), ACE(I/D), and CAPN10(3R/2R)—on T2D risk, through a meta-analysis combining data of previous studies performed on Tunisian popula…
Human Alu Insertion Polymorphisms in North African Populations
Several features make Alu insertions a powerful tool used in population genetic studies: the polymorphic nature of many Alu insertions, the stability of an Alu insertion event and, furthermore, the ancestral state of an Alu insertion is known to be the absence of the Alu element at a particular locus and the presence of an Alu insertion at the site that forward mutational change. This study analyses seven Alu insertion polymorphisms in a sample o…
Allele frequencies for 15 autosomal STR markers in the Libyan population
The high informativity observed for these 15 STRs in a Libyan population demonstrates their usefulness for forensic and parental purposes
Genetic structure of Tunisian ethnic groups revealed by paternal lineages
Tunisia has experienced a variety of human migrations that have modeled the myriad cultural groups inhabiting the area. Both Arabic and Berber‐speaking populations live in Tunisia. Berbers are commonly considered as in situ descendants of peoples who settled roughly in Palaeolithic times, and posterior demographic events such as the arrival of the Neolithic, the Arab migrations, and the expulsion of the “Moors” from Spain, had a strong cultural i…
Mitochondrial DNA structure in North Africa reveals a genetic discontinuity in the Nile Valley
Human population movements in North Africa have been mostly restricted to an east‐west direction due to the geographical barriers imposed by the Sahara Desert and the Mediterranean Sea. Although these barriers have not completely impeded human migrations, genetic studies have shown that an east‐west genetic gradient exists. However, the lack of genetic information of certain geographical areas and the focus of some studies in parts of the North A…
Ancient Local Evolution of African mtDNA Haplogroups in Tunisian Berber Populations
Our objective is to highlight the age of sub-Saharan gene flows in North Africa and particularly in Tunisia. Therefore we analyzed in a broad phylogeographic context sub-Saharan mtDNA haplogroups of Tunisian Berber populations considered representative of ancient settlement. More than 2,000 sequences were collected from the literature, and networks were constructed. The results show that the most ancient haplogroup is L3*, which would have been i…
Substructure of a Tunisian Berber Population as Inferred from 15 Autosomal Short Tandem Repeat Loci
Currently, language and cultural practices are the only criteria to distinguish between Berber autochthonous Tunisian populations. To evaluate these populations' possible genetic structure and differentiation, we have analyzed 15 autosomal short tandem repeat loci (CSF1PO, D3S1358, D5S818, D7S820, D8S1179, D13S317, D16S539, D18S51, D21S11, FGA, TH01, TPOX, VWA, D2S1338, and D19S433) in three southern Tunisian Berber groups: Sened, Matmata, and Ch…
