Iranian Lurs Genetic Diversity: An Anthropological View Based

Background: HLA genes are highly polymorphic and certain alleles are frequent only in specific populations. Therefore, HLA is a unique tool for studying the genetic rela-tionship between different populations. Iranians are ethnically diverse people and one of the major ethnic groups in Iran is Lur population inhabiting along the central and southern parts of Zagros Chain Mountain. Objectives: Genetic relationship among three Lur subpopulations was investigated based on HLA class II profiles. Methods: HLA typing was performed using PCR/RFLP and PCR/SSP methods in 154 indi-viduals from three Lur subpopulation living in Luristan, Kohkiloyeh / Boyerahmad, and Chahar-Mahal / Bakhtiari. Results: The most common DRB1 allele in Lurs of Luristan and Kohkiloyeh / Boyerahmad was *1103=4 while DRB1*0701 was the most common allele in Bakhtiaris. DQA1*0501 and DQB1*0301 were the most fre-quent alleles and DRB1*1103=04-DQA1*0501-DQB1*0301 was the predominant haplotype in the three studied subpopulations.
