gb PHARM DPYD*2A
The kit is intended for detection of mutation DPYD*2A (IVS14+1G>A) in gene for dihydropyrimidine dehydrogenase in human genomic DNA by real-time PCR method (allelic discrimination).
Fluoropyrimidines (5-fluorouracil and its prodrugs capecitabine and tegafur) are the basic drugs used in chemotherapy of gastrointestinal cancer. Their use is limited by development of many toxic effects including life-threatening myelosuppression. Dihydropyrimidine dehydrogenase (DPD) catalyzes the initial step of pyrimidines catabolism.
It inactivates fluoropyrimidine chemotherapeutics and its activity influences the frequency of toxicity. It is not recommended to administer the fluoropyrimidines to the patients with DPD deficiency. When studying polymorfisms of the gene for DPD (DPYD), the relationship between presence of particular mutations and decreased activity of DPD has been demonstrated. The allelic variant DPYD*2A (rs3918290) is the thoroughly studied mutation of DPYD. Its presence results in production of nonfunctional enzyme that is considered as the essential cause of the fluoropyrimidines toxicity. When the presence of mutated allele in the patient genome is proven, dose reduction or alternative chemotherapy is recommended.
