Abstract

The invention relates to the technical field of gene polymorphism detection, and in particular relates to a sequencing primer, a kit and a detection method for detecting CYP2C19 gene polymorphism, which aim at overcoming the defects that a DNA microarray chip method for detecting CYP2C19 gene polymorphism is long in consumed time, relatively high in cost and inflexible in use in the prior art. The sequencing primer provided by the invention is the one for detecting CYP2C19*17 gene polymorphism, and the 3'-end base sequence of the sequencing primer is -TTGTGTCTTCTGTTCTCAA-3'. The kit provided by the invention is short in detection time, low in detection cost, flexible in use and very high in detection precision. The detection method provided by the invention is easy in operation.

Description

technical field [0001] The invention relates to the technical field of gene polymorphism detection, in particular to a sequencing primer, a kit and a detection method for detecting CYP2C19 gene polymorphism by pyrosequencing. Background technique [0002] Different individuals have great differences in the response, toxicity and therapeutic effect of drugs. There are many reasons for this individual difference. Among them, the gene polymorphism of drug metabolizing enzymes may lead to the drug efficacy and adverse reactions of many drugs in treatment. A cause of individual differences. With the continuous deepening of pharmacogenomics research, the study of the differences in individual allelic polymorphisms affecting individual responses to drugs has become a research hotspot at home and abroad. [0003] Cytochrome P450 (cytochrome P450, CYP450) enzyme system is an important drug-metabolizing enzyme in the human body, among which CYP2C19 is an important isoenzyme of the CY...
