CCR5-Δ32 gene variant frequency in the Turkish Cypriot population.

Recent UNAIDS reports (December 2019) indicate that 37.9 million people have been affected by HIV infection around the globe in 2018, of which 1.7 million are cited as new infections. Human immunodeficiency virus-1 (HIV-1) requires both the CD4 receptor, as the primary receptor, and a chemokine co-receptor to gain entry into the cell. In addition to the WT allele for C-C motif chemokine receptor 5 (CCR5-wt), there is another allele with a 32 bp deletion in the protein coding region (CCR5-Δ32). Individuals who are homozygous for the mutant allele are resistant towards M-tropic HIV infections. In the current study, we aimed to determine the CCR5-Δ32 allele frequency in the Turkish Cypriot population with 326 subjects, 141 men (43.1%) and 185 (56.9%) women. The region of the CCR5 gene containing the Δ32 deletion was amplified using flanking primers. The CCR5 gene Δ32 allele frequency was calculated at 3% and only observed in heterozygous individuals. We hope that our current publication could be a point of dialog between the physicians, the government officials and the public set up a more modern and well-structured HIV screening program in an effort to control and hopefully eliminate HIV from the Turkish Cypriot population.
