| Popis: | Background: Phenylketonuria as the most common genetic metabolic disorder is the result of disruption of the phenylalanine hydroxylase gene. This study was carried out to explore the phenylalanine hydroxylase gene mutation status of Iranian phenylketonuria patients. Methods: Blood samples were collected from 30 patients, and hot spot areas of the phenylalanine hydroxylase gene, including exons 6, 7, 8, 11, and 12 were studied through polymerase chain reaction and sequencing techniques. Results: Eight different mutations, including 5 missense mutations, 1 splice mutation, 1 nonsense mutation, and 1 Silent/Splice mutation were detected. These mutations were R243X, R261Q, R261X, P281L, R241C, V399V, E280K, and IVS11+1G>C. V399V and R241C were reported for the first time in Iranian population. Three polymorphisms including Q232Q, V245V and L385L and 3 novel intronic variants including IVS10-15A>C, IVS6+44T>G, and IVS6+36 T>G were also detected in this study. Conclusion: The results of this study prove the heterogeneous status of phenylalanine hydroxylase gene mutations in the Iranian population, which can be useful in carrier testing and genetic counseling. |
