Description
Technical Field
The invention relates to application of a substance for detecting single nucleotide polymorphism, in particular to application of the substance for detecting single nucleotide polymorphism of mitochondrial DNA rs3937033 in personalized health care detection service.
Background
Single Nucleotide Polymorphism (SNP) refers to a variation of a single nucleotide in a genome, which is the most minute variation unit and is a variation form formed by substitution, inversion, insertion or deletion of a single nucleotide pair. Single nucleotide polymorphisms are a high density of genetic markers on the genome, with more than 3000 tens of thousands of SNPs found in the human genome. As a third generation genetic marker, the SNP has a large number and dense distribution, and is easy to detect, so the SNP is an ideal genotyping target. SNP typing detection has great significance in the research of disease genome (such as disease susceptibility), drug genome (drug effect, drug metabolism difference and adverse reaction), population evolution and the like.
Mitochondrial body contains a plurality of genetic materials, mitochondrial DNA (mtDNA), and mtDNA is an extracellular circular double-stranded DNA molecule consisting of an inner light chain (L) and an outer heavy chain (H). The total length of human mtDNA is 16,9bp, and the coding region is composed of coding region and non-coding region, and the function of coding region is to code 13 polypeptides related to oxidative phosphorylation, 2 groups of rRNA and 22 tRNAs. Because mtDNA has no intron, and mtDNA is expressed as maternal inheritance, and no histone is combined to protect the coding process, the mtDNA is easy to mutate, and can influence the genetic information carried by some important segments in a genome, and finally, diseases are caused.
The mitochondrial DNA T16519C single nucleotide polymorphism (rs 3937033) is a SNP site of a double-site polymorphism on human mitochondrial DNA, and the variation is a transition (T/C, A/G on its complementary strand). rs3937033 is located at MT:16519 (GRCh 38), HGVS: NC-012920.1 m.16519T >, located within the MT-D-loop gene.
High Altitude Pulmonary Edema (HAPE) is the most common acute severe altitude disease in the plateau region, and if the treatment is not timely carried out, the life of the patient is endangered, and the problem is also a big problem which troubles the highland combat troops of various countries. In recent years, a series of studies have been made on the pathogenesis of HAPE at home and abroad, and unfortunately, the pathogenesis is still unclear, and the possible mechanisms which are currently accepted more generally are: on the one hand, the pulmonary vessels and alveolar respiratory epithelium of sensitive individuals have some important functional defects due to congenital genetic or acquired factors, and may cause excessive hypoxic pulmonary hypertension upon acute hypoxic exposure, which is the most critical link in HAPE development. On the other hand, impairment of the body's ability to clear the alveolar fluid due to genetic defects and impaired sodium transport from hypoxia to the alveolar epithelium may be a non-negligible important aspect of the promotion of HAPE.

Claims (8)
1. The application of the substance for detecting the polymorphism or genotype of rs3937033 in the human genome in the preparation of products for detecting or assisting in detecting the risk of the high altitude pulmonary edema.
2. The application of the substance for detecting the polymorphism or genotype of rs3937033 in human genome in preparation of products for detecting or assisting in detection of susceptibility to high altitude pulmonary edema.
3. The application of the substance for detecting the polymorphism or genotype of rs3937033 in the human genome in preparing products for screening or assisting in screening susceptible individuals or non-susceptible individuals of high altitude pulmonary edema.
4. The application of the substance for detecting the polymorphism or genotype of rs3937033 in the human genome in the preparation of products for evaluating or assisting in evaluating the risk of the disease of the high altitude pulmonary edema.
5. Use according to any one of claims 1 to 4, characterized in that: the polymorphism or genotype of the rs3937033 is T or C, the T is the polymorphism or genotype of the site rs3937033 as T, and the C is the polymorphism or genotype of the site rs3937033 as C; and the risk of developing high altitude pulmonary edema of the individual with the rs3937033 polymorphism or genotype C is lower than or is candidate for the individual with the rs3937033 polymorphism or genotype T.
6. The application of the substance for detecting the polymorphism or genotype of rs3937033 in a human genome in preparing products for screening or assisting in screening the susceptible genotype or the non-susceptible genotype of plateau pulmonary edema.
7. Use according to claim 6, characterized in that: the susceptible genotype of the plateau pulmonary edema is T, and the non-susceptible genotype of the plateau pulmonary edema is C; the T is the genotype with the site of rs3937033 as the T, and the C is the genotype with the site of rs3937033 as the C.
8. Use according to any one of claims 1 to 7, characterized in that: the substance for detecting the polymorphism or genotype of the rs3937033 in the human genome contains a PCR primer and/or a single-base extension primer for amplifying a human genome DNA fragment including the rs 3937033.
