Genetic Passport: The Key to Understanding Health (Genetic Passport: Key to Understanding Health)
I. Fundamentals of a genetic passport
I.1 What is a genetic passport?
The genetic passport is an individual genetic profile obtained by analyzing human DNA. It contains information about the genetic characteristics, predispositions to various diseases, metabolic features, reaction to drugs and other genetically determined characteristics. This is not just a list of genes, but a comprehensive interpretation of genetic data, presented in a format convenient for understanding. The main goal of a genetic passport is to provide a person (and his doctor) with valuable information that allows you to make more conscious decisions regarding health, lifestyle and prevention of diseases.
I.2 How is the receipt of a genetic passport?
The process of obtaining a genetic passport begins with the collection of biological material. Most often, a sample of saliva or a small amount of blood is used. Then the sample is sent to a specialized genetic laboratory, where DNA is released from it. There are several DNA analysis technologies used to create a genetic passport:
- Microchips (DNA Microarrays): This method allows you to simultaneously analyze hundreds of thousands or even millions of genetic markers (one -unique polymorphism – SNPS). SNPS is the most common type of genetic variations, which is the differences in one nucleotide in a certain position in the genome. Microchips identify the presence or absence of certain SNPS, which allows you to evaluate the risk of various diseases and other genetic characteristics.
- New generation sequencing (NEXT-GENERATION SEQUENCING-NGS): NGS is a more modern and powerful technology that allows you to read a sequence of DNA with high accuracy and speed. NGS can be used to sequenize the entire genome (full genomic sequencing – WGS) or its individual sections (for example, encoding areas of genes – eczu sequencing – WES). NGS provides more complete information about genetic versions, including rare and previously not identified mutations.
- PCR (polymerase chain reaction) in real time (Real-Time PCR): This method is used to quickly and accurately determine the presence of specific genetic options. In real time, PCR is often used to analyze individual genes or SNPS associated with certain diseases or signs.
After DNA analysis, genetic data is interpreted using complex algorithms and databases containing information about the relationship between genetic options and various characteristics. The results of the interpretation are presented in the form of a genetic passport, which may include information about:
- Risks of the development of various diseases (for example, cardiovascular diseases, diabetes, cancer)
- Predisposition to certain conditions (for example, lactose intolerance, sensitivity to caffeine)
- Metabolic features (for example, the ability to absorb certain vitamins and minerals)
- Reactions to drugs (pharmacogenetics)
- Hereditary predisposition to certain signs (for example, sports abilities, type of physique)
I.3 Ethical and legal aspects of the genetic passport
The use of genetic information raises important ethical and legal issues. These include:
- Confidentiality: It is necessary to provide strict protection of genetic data from unauthorized access and use. Information about the genetic predisposition to diseases can be used to discriminate in the field of insurance, employment or credit.
- Informed consent: A person must receive complete and understandable information about the purpose, methods and possible consequences of genetic testing before giving consent to its conduct. It must be emphasized that a genetic passport is not an absolute diagnosis, but only indicates an increased risk of developing certain diseases.
- Genetic counseling: After receiving a genetic passport, it is recommended to contact a genetic consultant who will help interpret the results and develop an individual prevention and treatment plan. It is important to understand that a genetic passport is only one of the factors affecting health, and its results should be considered in a complex with other data, such as an anamnesis, the results of medical examinations and lifestyle.
- Accuracy and reliability: It is necessary to choose genetic laboratories using reliable and validated DNA analysis methods. The results of genetic testing should be verified and confirmed before making any decisions based on them.
- Genetic discrimination: It is necessary to legally prohibit genetic discrimination in the field of insurance, employment and other areas. People should not be discriminated against their genetic predisposition to diseases.
- Regulation: It is necessary to develop clear legal norms governing genetic testing, the use of genetic information and protecting patients.
II. Application of a genetic passport in various fields
II.1 Personalized medicine
A genetic passport is a key tool for personalized medicine, which involves an individual approach to the prevention, diagnosis and treatment of diseases. It allows you to take into account the genetic characteristics of each person when developing a treatment and prevention plan, which increases efficiency and reduces the risk of side effects.
- Pharmacogenetics: Pharmacogenetics studies the effect of genetic factors on the body’s reaction to drugs. A genetic passport can help determine which drugs will be most effective and safe for a particular person, as well as what doses of drugs should be used. For example, some people have genetic options that affect the metabolism of certain drugs, which can lead to a decrease in efficiency or increased risk of side effects. Pharmacogenetic testing allows you to predict these effects and choose the optimal treatment regimen.
- Prevention of diseases: A genetic passport can reveal a predisposition to various diseases, which allows you to develop an individual prevention plan, including changes in lifestyle, diet, physical exercises and regular medical examinations. For example, if a genetic passport shows an increased risk of developing cardiovascular diseases, a person can take measures to reduce risk, such as rejection of smoking, reducing cholesterol and control of blood pressure.
- Diagnosis of diseases: In some cases, a genetic passport can help in the diagnosis of diseases, especially hereditary ones. The identification of genetic mutations associated with certain diseases can confirm the diagnosis and determine the tactics of treatment.
- Cancer treatment optimization: Genetic tumor testing can help determine the most effective methods of cancer treatment. An analysis of genetic mutations in tumor cells allows you to choose targeted drugs that affect certain targets in tumors and block its growth and distribution.
II.2 Sports and Fitness
A genetic passport can provide valuable information for athletes and people involved in fitness. It can help determine the predisposition to certain sports, the optimal training mode and diet, as well as the risk of injuries.
- Definition of sports abilities: A genetic passport can identify genetic options associated with various sports abilities, such as strength, endurance, speed and coordination. This allows athletes to choose sports in which they have the greatest genetic potential.
- Optimization of the training process: A genetic passport can help develop an individual training plan taking into account the genetic characteristics of a person. For example, some people have a genetic predisposition to faster recovery after training, while others need more time to restore. A genetic passport can also help determine the optimal intensity and duration of training.
- Individual diet for athletes: A genetic passport can help develop an individual diet for athletes, taking into account their genetic characteristics and needs of the body. For example, some people have a genetic predisposition to a deficiency of certain vitamins and minerals, which can affect their sporting results. A genetic passport can also help determine the optimal ratio of macronutrients (proteins, fats and carbohydrates) in the diet.
- Prevention of injuries: A genetic passport can identify genetic options associated with an increased risk of sports injuries, such as bursts of ligaments and fractures. This allows athletes to take measures to reduce the risk of injuries, such as strengthening muscles and joints, using protective equipment and compliance with the correct technique of performing exercises.
II.3 dietetics and nutrigenetics
Nutrigenetics studies the interaction between genes and nutrients. A genetic passport can help develop an individual nutrition plan, taking into account the genetic characteristics of a person and his need for nutrients.
- Determination of individual needs for nutrients: A genetic passport can reveal genetic options that affect the assimilation and metabolism of certain vitamins, minerals and other nutrients. For example, some people have a genetic predisposition to vitamin D deficiency, which can lead to weakening of bones and other health problems. A genetic passport can also help determine the optimal consumption of macronutrients (proteins, fats and carbohydrates), depending on the genetic characteristics of a person.
- Identification of food intolerance: A genetic passport can reveal a genetic predisposition to intolerance to certain food products, such as lactose, gluten and fructose. This allows people to avoid these products and prevent unpleasant symptoms, such as bloating, diarrhea and abdominal pain.
- Weight control: A genetic passport can help develop an individual nutrition plan for weight control, taking into account the genetic characteristics of a person and his metabolism. Some people have a genetic predisposition to weight gain, while others are easy to maintain normal weight. The genetic passport can also help determine the optimal ratio of macronutrients in the diet to maintain healthy weight.
- Personalized nutrition recommendations: A genetic passport may provide personalized nutrition recommendations based on the genetic characteristics of a person and his goals for health. These recommendations may include information about which products should be consumed in larger quantities, and which should be avoided, as well as what nutritional supplements can be useful.
II.4 Dermatology and Cosmetology
A genetic passport can provide valuable information for dermatologists and cosmetologists, which allows you to develop individual skin care programs that take into account the genetic characteristics of a person.
- Determination of skin type: A genetic passport can reveal genetic options associated with various types of skin, such as dry, oily, combined and sensitive. This allows dermatologists and cosmetologists to recommend products and procedures that are most suitable for a specific type of skin.
- Prevention of skin aging: A genetic passport can identify genetic options associated with the process of skin aging, such as wrinkles, loss of elasticity and pigmentation. This allows dermatologists and cosmetologists to recommend products and procedures aimed at slowing down the skin aging process.
- Sun protection: A genetic passport can reveal a genetic predisposition to damage to the skin under the influence of solar radiation. This allows dermatologists and cosmetologists to recommend products and procedures aimed at protecting the skin from the sun.
- Treatment of skin diseases: In some cases, a genetic passport can help in the treatment of skin diseases such as acne, eczema and psoriasis. The identification of genetic mutations associated with these diseases can help develop an individual treatment plan.
II.5 Reproductive health
The genetic passport plays an important role in reproductive health, helping pairs plan pregnancy and prevent the birth of children with genetic diseases.
- Prenatal screening: A genetic passport can be used for prenatal screening to detect genetic diseases in the fetus. This allows parents to decide on the continuation or termination of pregnancy.
- Pregnancy planning: A genetic passport can help pairs plan pregnancy, revealing genetic diseases that can be transmitted to the child. If both parents are carriers of the same genetic disease, there is a risk of a child with this disease. Genetic testing allows pairs to learn about their risk and take measures to prevent the birth of a child with a genetic disease, such as the use of donor sperm or eggs, conducting pre -implantation genetic diagnostics (PGD) or prenatal screening.
- Risk assessment of infertility: A genetic passport can help assess the risk of infertility in men and women. Some genetic options can affect fertility and increase the risk of infertility. The identification of these options allows pairs to contact a specialist in reproductive health and get the necessary treatment.
