Abstract

The invention discloses a kit for rapid detection of polymorphism of a Warfarin metabolic enzyme gene by virtue of a pyrosequencing method. The kit consists of three pairs of specific amplification primers and three sequencing primers; the three pairs of specific amplification primers include two genes, namely a CYP2CP gene and a VOKRC1 gene, wherein the CYP2CP gene contains two pairs of primers; the three sequencing primers specifically relate to three single nucleotide polymorphisms, namely CYP2C9*2, CYP2C9*3 and VKORC1 (-1693); and the nucleotide sequences are as shown in SEQ ID NO.1-9. The detection method disclosed by the invention is not only high in sensitivity, but also direct in result, and simpler, rapider and more accurate in interpretation; the kit is capable of achieving accurate, rapid and high-throughput detection of the Warfarin metabolic enzyme gene; and the kit is relatively high in popularization and application values in personalized medicine.

Description

technical field [0001] The invention belongs to the technical field of molecular diagnosis, and in particular relates to a kit for rapidly detecting gene polymorphisms of warfarin metabolic enzymes by pyrosequencing and an application thereof. Background technique [0002] Warfarin is a coumarin-based oral anticoagulant commonly used in clinical treatment of thrombotic diseases, which has dual effects of anticoagulation and thrombolysis. The anticoagulant therapeutic index range of warfarin is narrow. If the dose is insufficient, the therapeutic effect will not be achieved, and if the dose is slightly excessive, it will cause bleeding, and in severe cases, it will endanger the patient's life. However, there are obvious individual differences and racial differences in the plasma drug concentration and efficacy of warfarin. Studies have shown that the dose of anticoagulant warfarin used by different patients can vary by 20 times, and the maintenance dose of Asians is higher th...
