GENETIC POLYMORPHISM. VALUE. METHODS OF RESEARCH
99,9% of the genes are the same for all people. The individual characteristics of each of us were called genetic polymorphism, determined only by 0,1% of the genes and manifested in the form of single nucleotide polymorphism, restriction fragment length polymorphism, and short tandem repeats. The possibility of sequencing of individual genomes introduces an individual approach to the treatment and prevention of human diseases and represens the fundamental basis of personalized medicine. The latter takes into account the peculiarities of the genomes of individuals, determining the person's predisposition to develop some diseases. Based on the analysis of genetic polymorphisms, it is possible to create a genetic passport, which is an individual DNA database, reflecting the unique genetic characteristics of each person, his predisposition to certain hereditary, multifactor and other diseases.
