GT HapScreen® PAH
For more accurate and risk free prenatal diagnosis of Phenylketonuria
Phenylketonuria (PKU) is a commonly inherited metabolic disorder. The disease is inherited as an autosomal recessive pattern. Mutations in the PAH (phenylalanine hydroxylase) gene are responsible for the classical type of the disease. More than 500 mutations have been found to cause the disease. Carrier screening, neonatal screening, as well as prenatal diagnosis, is in practice in most countries.
The GT HapScreen® PAH kit has been developed to aid carrier detection as well as prenatal diagnosis of Phenylketonuria (commonly known as PKU). The kit functions based on STR markers and QF-PCR technique to aid prenatal diagnosis via haplotyping and linkage analysis. Therefore, the use of STR based haplotyping, makes prenatal diagnosis more accurate and more reliable.
Kit components include multiplex PCR primers which are designed from the PAH gene, enzyme, PCR master mix, calibration matrix standard and size standard. The STR markers designed for 7 regions that cover the upstream, downstream and intron of the PAH gene. This kit is optimized to work with DNA samples purified mainly from blood, amniotic fluid, and chorionic villus (CVS).
Along with PKU detection, the GT HapScreen® PAH kit includes autosomal STR markers used for QF-PCR to detect aneuploidies of chromosomes 21, 18, 13, X and Y as well as sex typing. There are many advantages outlined in the introduction section of GT HapScreen® kits.
