Mutation analysis of Phenylalanine hydroxylase gene in Iranian patients with Phenylketonuria

Mutations of the phenylalanine hydroxylase gene in Iranian Azeri Turkish patients with phenylketonuria.

AIM Phenylalanine hydroxylase (PAH) deficiency is caused by mutations in the PAH gene resulting in a primary deficiency of the PAH enzyme activity, intolerance to the dietary intake of phenylalanine (Phe), and production of the phenylketonuria disease. To date there have been no reports on the molecular analysis of phenylketonuria in the Iranian Azeri Turkish population. In this study, a total ...

Mutations of the phenylalanine hydroxylase gene in Iranian patients with phenylketonuria

Phenylketonuria (PKU) is an autosomal recessive disease which results from mutations in the phenylalanine hydroxylase (PAH) gene. The aim of this study was the identification of sixteen different mutations in Iranian patients with hyperphenylalaninemia. The mutations were detected during the characterization of PAH genotypes of 39 PKU patients from Qazvin and Zanjan provinces of Iran. PAH mutat...

Identifying Variable Number of Tandem Repeat Alleles in Phenylalanine Hydroxylase Gene in Patients with Phenylketonuria in Golestan Province, Iran

Background and Objective: Phenylketonuria (PKU) is a metabolic disorder that is caused by mutations in the phenylalanine hydroxylase (PAH) gene. The multiplicity of mutations in the PAH gene of PKU leads to the cases, in which the pathogenic mutation cannot be detected. In these cases, the variable number of tandem repeat (VNTR), which is the polymorphic marker associated with the PAH gene, is ...

Novel mutation in exon 7 of phenylalanine hydroxylase gene in a Chinese patient with phenylketonuria.

Mutation analysis of the phenylalanine hydroxylase gene in Azerbaijani population, a report from West Azerbaijan province of Iran

Objective(s):Phenylketonuria (PKU) is a genetic inborn error of phenylalanine (Phe) metabolism resulting from insufficiency in the hepatic enzyme, phenylalanine hydroxylase (PAH), which leads to elevated levels of Phe in the blood. The present study was carried out for mutation analysis of the PAH gene in West Azerbaijan province of Iran. Materials and Methods:A total of 218 alleles from 40 PKU...

Mutations of the phenylalanine hydroxylase gene in patients with phenylketonuria in Shanxi, China

The variation in mutations in exons 3, 6, 7, 11 and 12 of the phenylalanine hydroxylase (PAH) gene was investigated in 59 children with phenylketonuria (PKU) and 100 normal children. Three single nucleotide polymorphisms were detected by sequence analysis. The mutational frequencies of cDNA 696, cDNA 735 and cDNA 1155 in patients were 96.2%, 76.1% and 7.6%, respectively, whereas in healthy chil...
