Description

A set of probes and a kit for constructing a library for detecting polymorphism of CYP3A5 gene related to pharmacogenomics by utilizing hybridization capture method
Technical Field
The invention relates to a group of probes and a database-establishing kit for detecting polymorphism of CYP3A5 gene related to pharmacogenomics by utilizing a hybridization capture method.
Background
With the gradual popularization of accurate medical treatment in recent years, pharmacogenomics (PGx) has been rapidly developed as a powerful means for achieving personalized medicine administration. PGx the main research on gene polymorphism affecting individual differences of drug reactions (including curative effects and adverse reactions) relates to genes encoding drug metabolizing enzymes, transporters, action targets and the like.
The cytochrome P450 (CYP 450) family is a family of isoenzymes associated with 90% of clinical drug metabolism. CYP450 metabolic enzymes are mainly responsible for the drug clearance phase I response and are the rate limiting step in drug metabolism, so genes encoding the CYP450 family are the most relevant genetic factors to substrate pharmacokinetics. The human has 18 CYP450 enzyme gene families and 43 subfamilies, and enzyme systems related to the metabolism of most medicaments mainly comprise three families of CYP1, CYP2 and CYP 3. Among them, CYP3A subfamily members have prominent actions, maximum content and large substrate spectrum, and are the most main rate-limiting enzymes in drug metabolism reaction.
The human CYP3A5 gene is located on chromosome 7, has a total length of 31.8kb, comprises 13 exons, and encodes a protein consisting of 502 amino acids. It is one of the most active enzymes in the P4503A family, and it has become a medical research focus because the Single Nucleotide Polymorphism (SNP) of the gene can lead to different metabolic activities of the drug, and different SNPs may also be associated with genetic susceptibility to certain diseases.
The results of the study on genetics suggest that 20% -95% of individual differences in drug response and primary treatment are caused by genetic factors. The CYP3A5 gene and phenotype of the primary patient can be detected to predict the curative effect, prognosis, adverse reaction and the like of the drug treatment, so that the individual drug administration is guided, and the optimal treatment purpose is achieved. For organ transplantation patients, the CyP3A5 genotype is used as the basis of the immunosuppressant personalized treatment, so that the initial dosage of the tacrolimus drug is determined, passive monitoring is changed into active prediction, the incidence rate of acute rejection after transplantation and the toxicity and adverse reaction of the drug can be effectively reduced, and the survival rate of transplanted organs is further improved.
Currently, methods commonly used for detecting CYP3A5 gene polymorphism include DNA sequencing, restriction fragment length polymorphism polymerase chain reaction (PCR-RFLP), high Performance Liquid Chromatography (HPLC), capillary electrophoresis (Capillary Electrophoresis), and the like. The methods have the defects of complex operation, long time consumption, high cost, low detection sensitivity, easiness in causing false positive or false negative and the like.
With the continuous accumulation of pharmacogenomic knowledge and the continuous development of molecular detection techniques, multi-site/multi-drug personalized drug detection is being accepted by the industry. The genetic information of the drug metabolizing enzyme and the action target gene of the common drugs or the drugs (such as cardiovascular and immunosuppression) can be obtained by one-time detection, and the genetic information has decisive influence on the formulation of the personalized medication scheme of drug dosage, drug type selection, drug interaction and the like.
The currently PGx in-vitro diagnostic reagent for obtaining three types of evidence lot cannot cover the gene locus required to be detected clinically, and along with the popularization of the second-generation sequencing technology, high-throughput sequencing can simultaneously sequence millions or even billions of DNA fragments, so that the detection of hundreds of related genes, whole exons and whole genome of pharmacogenomics can be carried out at one time at lower cost, and the required sample size is not increased. The high-throughput sequencing technology has wide application value in the detection of drug metabolizing enzyme and drug action target gene due to the advantages of throughput, cost and efficiency.
