HLA genetic study from United Arab Emirates (UAE), Abu Dhabi.

Emiratis belong to the United Arab Emirates (UAE) country. UAE is placed at the East part of the Arabian Peninsula, protruding into the Arabia Gulf and was populated since 130,000 years ago. First humans migrating out of Africa went probably across this territory. HLA-A, -B, -C, -DRB1, -DQB1, -DQA1 were typed in order to obtain HLA profile for clinical, epidemiological and population genetics studies. Twenty different HLA-A, thirty-five HLA-B and twenty-two HLA-C class I alleles were detected; twenty-seven different HLA-DRB1, fourteen HLA-DQB1 and twelve HLA-DQA1 class II alleles were found. Most frequent extended HLA haplotypes are also depicted. People are present in this area since prehistoric ages according to archaeological studies; the "Out of Africa" eastern migration may have affected the present day population composition.
