What is Gene Polymorphism Testing?

Humans are initially formed from a fertilized egg, which is formed by the combination of an egg and a sperm. The fertilized egg also contains the chromosomes and DNA of the father and mother, which are also called genes. Genes are constantly transcribed and translated, and then denatured, thus forming various different people. Let’s take a look at what genetic polymorphism testing is.

There are more than 85 types of HPV identified in the human body. Among them, there are more than 20 types related to the occurrence of cervical cancer, which can be divided into three types: high-risk, medium-risk and low-risk. Among them, high-risk types such as HPV16 and HPV18 are closely related to cervical cancer.

Currently commonly used treatments such as drug therapy, laser therapy, surgical treatment, etc. cannot effectively eliminate latent viruses in the human body. They only eliminate surface symptoms, and genital warts are prone to recurrence.

Now there is a

Mature diagnosis and treatment techniques can completely eliminate latent viruses in the human body in a short period of time and achieve the goal of complete cure. Some commonly used methods for treating genital warts in society only target surface symptoms. The latent viruses in the human body cannot be removed, and the money is wasted without curing the disease. In order to successfully treat genital warts, you must go to a regular hospital for scientific treatment in time.

Genetic diagnosis is the etiology diagnosis of diseases at the gene level. This diagnostic method first obtains genomic DNA, that is, separates and purifies the DNA, and then detects the DNA. The techniques for detecting DNA include PCR technology, nucleic acid hybridization technology, and the combination of PCR and nucleic acid hybridization. The traditional diagnostic method is based on the phenotypic changes of the disease, but the phenotypic changes are not special in many cases, and the time of appearance is often late, which sometimes makes it impossible to make a clear diagnosis and delays the treatment of the disease. However, the phenotypic changes of the disease are based on gene changes, so genetic diagnosis can not only make an accurate diagnosis of certain diseases, but also make a pre-symptom diagnosis. At present, genetic diagnosis can clearly locate the causative gene, the type and degree of the defect for hereditary diseases;

For genetically related diseases or diseases with genetic tendency, the purpose of auxiliary diagnosis can be achieved through linkage analysis of related genes; for infectious diseases caused by pathogenic microorganisms and parasites, it can be diagnosed whether the pathogens are still present; human leukocyte antigen (HLA) gene typing can be performed to provide a scientific basis for tissue matching for organ transplantation. In addition, genetic diagnosis can also be used to monitor whether water, soil, atmosphere, food, etc. are contaminated by pathogens; kinship identification, personal identification for public security, procuratorial and judicial purposes, gender identification and species identification can be performed through the detection of human gene polymorphism.
