Phenylketonuria from genetics to clinics: An Iranian prospect
Author(s):
Abstract:
Phenylketonuria (PKU) is the most common autosomal recessive disorder of amino acid metabolism. The disease is caused mainly by mutations in the phenylalanine hydroxylase (PAH) gene, encoding phenylalanine hydroxylase (PAH) enzyme. The PAH enzyme deficiency results in the elevation of phenylalanine in the blood, which may cause severe irreversible mental retardation in the affected individuals. More than 500 different disease causing mutations have been identified in the PAH gene. Direct and indirect molecular approaches have been developed for carrier detection and prenatal diagnosis of PKU disease. Population distribution of the PAH gene mutations and the PKU disease varies in different countries. In view of relatively high prevalence of the disease in Iranian population, investigations toward the elucidation of molecular aspects of the disease were required. In the present article, clinical and molecular basis of the PKU disease, with emphasis on the studies performed in Iranian population, were reviewed.
