Problems solved by technology

A number of current studies have shown that the polymorphism of this site will weaken the performance of the transcription factor complex that ERCC2 participates in, thereby reducing the ability to repair DNA damage, and the ability of transcription factors will also decrease at the same time, resulting in a series of Occurrence of diseases such as lung cancer, prostate cancer, etc.

Embodiment 2

[0043] Example 2. Services that guide people to proactively prevent lung cancer

[0044] At present, Shanghai Zhujian Bioengineering Co., Ltd. has launched this service.

[0045] Step 1: DNA Extraction

[0046] The subjects were consulted before the service, and the subjects signed the informed consent and filled out the questionnaire on living and eating habits. According to the instructions in the sampling box, the oral epithelial cells were sampled with oral swabs, and the DNA of the oral epithelial cells was extracted by silica gel adsorption.

[0047] Step 2: Genotyping Assays

[0048] Using the kit provided by the present invention, the SNP site rs1048943 on the CYP1A1 gene and the SNP site rs1799793 on the ERCC2 gene are simultaneously detected by fluorescent quantitative PCR to determine the genotypes of the two SNPs sites.

[0049] Step 3: Instruct people to be proactive in preventing lung cancer

[0050] Through the analysis of the SNPs genotype of the tested sub...

Abstract

The invention discloses a reagent box for detecting lung cancer susceptibility. The reagent box comprises a pair of specificity primers for detecting concurrently no. rs1048943 SNP site of CYP1A1 gene and no. rs1799793 SNP site of ERCC2 gene, a specificity fluorescent probe and an ordinary assembly for fluorescent quantitative PCR detection. The reagent box predicts the susceptibility of individuals on lung cancer by detecting and analyzing currently the type of carried gene at SNPs site of individual CYP1A1 and ERCC2 gene.

Description

technical field [0001] The present invention relates to a kit for detecting disease susceptibility, especially a kit for detecting susceptibility to lung cancer. Single nucleotide polymorphism (SNP) site and excision repair complex 2 (Excision Repair Cross-complementing Rodent Repair Deficiency, Complementation Group 2, ERCC2) single nucleotide polymorphism site to predict the individual's risk of lung cancer susceptibility. Background technique [0002] Primary bronchial lung cancer, referred to as lung cancer, is one of the most common malignant tumors in the world and a serious threat to human health and life. Tumor cells originate from the bronchial mucosa or glands, and often have regional lymph node and hematogenous metastasis. In the early stage, respiratory symptoms such as irritating cough and blood in the sputum are often present. The speed of disease progression is related to the biological characteristics of the cells. [0003] For half a century, the morbidity...
