Embodiment 1

[0048] Example 1 Design of primers for the rs2066853 site in the coding region of the AHR gene

[0049] 1. Primer design

[0050] In this implementation, the amplification primers and Taqman-MGB probes shown in Table 1 below were designed according to the upstream and downstream sequences of the rs2066853 SNP site on the AHR gene by comparing the sequences of the coding regions of the AHR gene.

[0059] Example 2 Application of rs2066853 site detection method in the detection of lung cancer susceptibility

[0060] 1. Extraction of DNA

[0061] The subjects were consulted before the service, and the subjects signed the informed consent and filled out the questionnaire on living and eating habits. 5ml of EDTA anticoagulated blood was extracted by conventional method. Genomic DNA of blood samples was extracted by silica gel adsorption method.

[0062] 2. Genotyping detection

[0063] Using the detection method of Example 1, the rs2066853 polymorphic site in the AHR gene coding region of the DNA of the subject to be tested was detected by fluorescent quantitative PCR to determine the genotype of the site.

[0064] 3. Guide people to actively prevent lung cancer

[0065] Through the analysis of the genotype of the tested person, the genotyping test report and the individualized health guidance report for the tested person are issued. The genotyping test report details ...

Abstract

The invention discloses a primer set for detecting the genotype of an rs2066853 site and a detection kit and application thereof. The primer set comprises a pair of specific primers, a wild-type fluorescent probe and a mutant fluorescent probe, and the sequences thereof are sequentially shown as SEQ ID NOs: 1-4; a detection method comprises the following specific steps: S1, extracting DNA from a sample to be detected; S2, with the DNA in the step S1 as a template, performing fluorescent quantitative PCR detection by using the primers to determine the genotype of the rs2066853 site; through the genotype of the site, lung cancer susceptibility assessment can be performed, and if the genotype of the rs2066853 site is A, the sample is susceptible to lung cancer. The rs2066853 site detecting primers designed by the invention are strong in specificity and high in amplification efficiency; the adopted detection method is simple, convenient and efficient; automatic result judgment is achieved; the primer set has a relatively good application prospect in disease prevention and detection.

Description

technical field [0001] The invention belongs to the field of biotechnology. More specifically, it relates to a primer set for detecting the genotype of the rs2066853 site, a detection kit and applications thereof. Background technique [0002] Lung cancer is one of the malignant tumors with the highest morbidity and mortality in the world, which seriously threatens human health and life safety. [0003] The latest research data shows that there are approximately 1.8 million new cases of lung cancer each year worldwide; while in my country, the number of new lung cancer patients reached 733,000 in 2015. Because lung cancer is often accompanied by early metastasis, 70% of lung cancer patients are found in advanced stage, and the current average 5-year survival rate is only 16%. In recent years, the incidence and mortality of lung cancer have been increasing year by year, and it has become a serious social public health problem.
