Considering the notion that Iranian population is one of the most heterogeneous i the world, this study was conducted to evaluate the association of VNTR-STR mini-haplotypes with the PAH gene mutations in PKU patients in Kermanshah province. Methods: A total of 24 unrelated Kurdish PKU patients with the known PAH gene causing mutations and 72 healthy controls were selected. The DNA fragments containing VNTR and STR systems were amplified by polymerase chain reaction (PCR). For VNTR system, PCR products were separated using electrophoresis on 2.5% agarose gel. For STR system, the samples were analyzed using DNA sequencing analysis version 5.2 software. Results: Overall, 5 PAH-VNTR-alleles, including VNTR3, 7, 8, 9, 12, and 3 PAH-STR-alleles, including STR238, 242, and 250, were detected in this study. VNTR3 and 8 alleles had the most frequency among healthy controls. Also, 6 different mini-haplotype alleles were found to be associated with PKU chromosomes. The 2 most prevalent mutations in Kermanshah province, IVS2+5G>C and IVS9+5G>A, were strongly linked to mini-haplotypes 9/242 and 8/238, respectively. Conclusion: The distributions and frequencies of VNTR alleles in Kurdish population have the most similarity to alleles previously described in European Caucasian families. Moreover, since the most common mutations in Kermanshah PKU chromosomes are rare and this was the first study on mini-haplotypes VNTR/STR among Iranian Kurdish PKU patients, given that this study was the first of its kind, it was not possible to compare its results with that of other studies on Iranian and non-Iranian populations. }, URL = {http://mjiri.iums.ac.ir/article-1-4838-en.html}, eprint = {http://mjiri.iums.ac.ir/article-1-4838-en.pdf}, journal = {Medical Journal of the Islamic Republic Of Iran}, doi = {10.47176/mjiri.33.88}, year = {2019} }
