Typical Health Risks Identified by Genetic Testing
1. Risk of Cardiovascular Disease
Cardiovascular disease is one of the leading causes of death in Japan, and many genes are associated with the risk. In particular, mutations in the APOE gene are known to increase the risk of heart attack and atherosclerosis. This genetic test can help you improve your lifestyle and reduce your risk at an early stage.
Preventive measures: If the genetic test reveals that you are at high risk, it is recommended that you adopt a diet, exercise, quit smoking, and manage stress. In addition, in consultation with a physician, the use of medications to manage blood pressure and cholesterol should be considered.
2. Cancer Risk
Although cancer is related to both genetic and environmental factors, genetic testing often identifies a risk of breast and ovarian cancer due to mutations in BRCA1 and BRCA2. Finding mutations in certain cancer genes can lead to early screening and preventive surgery.
Preventive measures: If your genes are found to put you at risk for cancer, you should increase the frequency of regular physical examinations and cancer screenings to ensure early detection. Lifestyle modification, smoking cessation, and maintenance of a healthy diet can also help prevent cancer.
3. Risk of Diabetes
The risk of developing diabetes is also associated with multiple genetic mutations, and genetic testing can assess the likelihood of developing the disease in advance. Genes such as TCF7L2, in particular, are related to insulin function and glucose metabolism and increase the risk of type 2 diabetes.
Preventive measures: If you are found to be at high risk, diet, exercise, and regular blood glucose monitoring can help delay or prevent the onset of the disease.

Advantages and Cautions of Genetic Testing
Benefits
- Promotes personalized medicine: The information obtained through genetic testing is important to help physicians tailor treatment plans to an individual’s constitution and risk.
- Early Prevention: Identification of risk allows early preventive measures to be taken before the onset of the disease.
- Providing information to family members: Since the risk of genetic disease can affect family members, information is provided that family members can use to manage their health.
Points to Note
- Avoid excessive worry: Even if a genetic test reveals a risk, it is important not to be overly anxious, as it is not certain that the disease will develop.
- Protecting the privacy of genetic information: Genetic information is very private, so it is necessary to choose a testing organization that manages the data well.
Preventive Medicine Using Genetic Test Results
The use of genetic testing as part of preventive medicine can greatly improve the management of health risks. For example, the following preventive measures can be taken:
- Lifestyle modification: Improving daily habits such as diet, exercise, and sleep are known factors that reduce the risk of disease.
- Reinforcement of regular health checkups: Effective for early detection of cancer, cardiovascular disease, and other diseases.
- Promoting medical consultation: If a risk is identified, it is recommended to consult a medical specialist and receive appropriate guidance.
The Future of Genetic Testing
Genetic testing has the potential to help further the development of personalized medicine and the early prevention of disease. In particular, advances in AI technology will enable faster and more accurate risk assessment, further brightening the future of medicine.
