Validation of New Allele-Specific Real-Time PCR System for Thiopurine Methyltransferase Genotyping in Korean Population

INTRODUCTION Thiopurine drugs are metabolized via S-methylation and catalyzed by thiopurine S-methyltransferase (TPMT). Patients with very low TPMT activity are at high risk of fatal bone marrow toxicity when standard doses of thiopurine drugs are administered. TPMT genotyping can predict TPMT activity and is not affected by transfusion or red blood cell defects. Here, we report a new allele-sp...

Validation of a genus-specific gene; TPS, used as internal control in quantitative Real Time PCR of transgenic cotton

Identification of genes with invariant levels of gene expression is a prerequisite for validating transcriptomic changes accompanying development. Ideally expression of these genes should be independent of the morphogenetic process or environmental condition.We report here the validation of internal control gene i.e.TPS (trehalose 6-phosphate-synthase) in cotton (Gossypium spp), using TaqMan sy...

A Real-Time RT-PCR Assay for Genotyping of Rotavirus Strains

Background: Human rotavirus (HRV) is the causative agent of severe gastroenteritis in children and responsible for two million hospitalizations and more than a half-million deaths annually. Sequence characteristics of the gene segments encoding the VP7 and VP4 proteins are used for the genotype classification of rotavirus. A wide variety of molecular methods are available, mainly based on rever...

Thiopurine methyltransferase genotyping in Palestinian childhood acute lymphoblastic leukemia patients

BACKGROUND The genetic polymorphism of thiopurine methyltransferase (TPMT) is well characterized in most populations. Four common polymorphic alleles are associated with impaired activity of the enzyme. These are TPMT*2 (238G>C), TPMT*3B (c.460G>A), TPMT*3A (c.460G>A and c.719A>G) and TPMT*3C (c.719A>G). The aim of the present study was to determine the frequency of TPMT polymorphisms and their...

High-throughput genotyping of thiopurine S-methyltransferase by denaturing HPLC.

BACKGROUND The thiopurine S:-methyltransferase (TPMT) genetic polymorphism has a significant clinical impact on the toxicity of thiopurine drugs, which are used in the treatment of leukemia and as immunosuppressants. To date, 10 mutant alleles are known that are associated with intermediate or low TPMT activity. To facilitate rapid screening of clinically relevant TPMT mutations, we developed a...
