Introduction: Apolipoprotein L1 (APOL1) gene’s risk variants located on chromosome 22 are newly discovered factors for the development of chronic renal failure among African-American. These risk alleles were developed on the African continent as an evolutionary defense against sleep sickness due to Trypanosoma brucei rhodesiense and then spread with human migrations.

Objectives: In the present study, we sought to examine these risk variants in a group of hemodialysis patients of Northwest of Iran.

Patients and Methods: Two hundred patients receiving hemodialysis in different centers of the city (Tabriz in Northwest of Iran) were allocated randomly from a total number of 825 patients. The assessment of APOL1 polymorphisms (rs73885319, rs60910145, and rs71785313) was conducted using polymerase chain reaction–restriction fragment length polymorphism (PCR-RFLP) method. Patients’ demographic data, history, and their biochemical parameters were recorded based on their last measurement.

Results: No proposed renal risk variants of APOL1 gene in our hemodialysis population were found. All the participants had a wild genotype.

Conclusion: The results of our study match with reports from Europe and Asia. In the paleoanthropological point of view, our results do not support African human migration hypothesis.  

Keywords: Chronic kidney disease, End-stage renal disease, Hemodialysis, Chronic renal failure, African-American, Apolipoprotein L1

Implication for health policy/practice/research/medical education:

The appearance of renal risk variants of APOL1 gene (G1, and G2) protect the host against African sleep sleekness; however, predispose carriers to kidney disease. In the present study, we did not find any of these variants in a group of hemodialysis population.
