The genotyping data from 73 unrelated individuals were analyzed for Shannon index, the effective allele number of the markers and neutrality test by use of PyPop and Popgene32 programs. The Shannon index for D6S2879 and D6S2806 markers in the studied population was 1.0372 and 0.8601, respectively. The Fnd value computed for D6S2879 and D6S2806 markers were also estimated -0.8449 and 0.9904, respectively. The results obtained from Ewens-Watterson test indicated that D6S2879 and D6S2806 markers were under balancing and directional selection in the Iranian populations, respectively. The data suggested the presence of a selection force on HLA-DRB1 gene region in the Iranian populations. https://tbj.ui.ac.ir/article_17419_17b1e5f99858948b5f39aa2582141213.pdf
