In this study, we aimed to investigate the current genetic diversity and provide additional insights into the origins of the Algerian population by analyzing the frequencies of HLA -A,-B,-DRB1,-DQB1 alleles and associated haplotypes. We analyzed 1,082 unrelated healthy Algerian individuals, who were potential kidney donors, recruited and assessed in the Immunology Department of CHU Mustapha in Algiers over a 10-year period (2009-2019). HLA genotyping was performed by Polymerase Chain Reaction Sequence Specific Primers (PCR-SSP). The allelic typing estimate and haplotype frequencies were calculated using the R studio® software and Haplotype frequency estimation from the website https://hla-net.eu/. We identified a total of 20 HLA-A alleles, 31 HLA-B alleles, 13 HLA-DRB1 alleles and5 HLA-DQB1 alleles. Regarding the allele frequency, the haplotype frequency and the distribution with other population database, we were able to provide a description of Algerian genetic background and draw some anthropogenetic conclusions. This study of HLA polymorphism in the Algerian population shows a strong genetic similarity with the populations of southern Europe and North Africa (Morocco, Tunisia and Libya) with which it has shared a common history since antiquity. In addition to its contribution to anthropogenetics, our study, serve as a reference database for studies exploring associations between the HLA system and certain pathologies.
