Application of natural and amplification created restriction sites for the diagnosis of PKU mutations.

چکیده
PCR amplification, either conventional, or as site directed mutagenesis using primers with mismatched 3'-ends, followed by restriction endonuclease digestion, provides rapid, non-isotope assays of known mutations in the human phenylalanine hydroxylase gene. Such assays were shown to have the potential to detect all of the 18 presently reported phenylketonuria mutations. The practical applicability of this approach was demonstrated for eight mutations in Norwegian phenylketonuria patients, among them the most common ones.

Phenylketonuria from Genetics to Clinics: An Iranian Prospect
Phenylketonuria (PKU) is the most common autosomal recessive disorder of amino acid metabolism. Thedisease is caused mainly by mutations in the phenylalanine hydroxylase (PAH) gene, encoding phenylalaninehydroxylase (PAH) enzyme. The PAH enzyme deficiency results in the elevation of phenylalanine inthe blood, which may cause severe irreversible mental retardation in the affect...
متن کاملRapid diagnosis of beta-thalassemia mutations in Chinese by naturally and amplified created restriction sites.
We developed a rapid and simple method to diagnose the molecular defects of beta-thalassemia in Chinese patients. This method involves the selective amplification of a DNA fragment from human beta globin gene with specific oligonucleotide primers, followed by digestion with restriction enzymes that recognize artificially created or naturally occurring restriction sites. To detect the 4-nucleoti...
متن کاملA New Enzymatic Method for Rapid Diagnosis of Phenylketonuria Using Alkaliphilic Bacillus
Rapid and in time diagnosis of phenylketonuria (PKU) in affected infants can help preventing the progress of mental and developmental disorders associated with the disease. Here we report the isolation of alkaliphilic Bacillus bacteria capable of producing high level of Phenylalanine dehydrogenase (PheDH) from soil. A new quantitative and rapid test for PKU diagnosis was then developed using th...
متن کاملIdentification and characterization of large deletions in the phenylalanine hydroxylase (PAH) gene by MLPA: evidence for both homologous and non-homologous mechanisms of rearrangement.
Large gene deletions and duplications were analyzed in 59 unrelated phenylketonuria (PKU) patients negative for phenylalanine hydroxylase (PAH) mutations on one or both alleles from previous exon by exon analysis. Using the novel multiplex ligation-dependent probe amplification (MLPA) method, a total of 31 partial PAH deletions involving single exons were identified in 31 PKU patients. Nineteen...
متن کاملMutation 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...
