Personalized medicine, also known as precision medicine, is revolutionizing the medical field by providing prevention, diagnosis, and treatment options based on an individual’s biological makeup. Leading the revolution in the medical field is hereditary testing, a genetic tool that provides an individual with access to information about their DNA, enabling the identification of inherited risk factors and individual biological makeups. Genetic differences are identified through hereditary testing, providing vital information that enables medical practitioners to make informed decisions based on an individual’s genetic makeup.

From One-Size-Fits-All to Precision Care
Conventional medicine normally operates under some guidelines that are established based on the average population. Although this has led to many advances in public health, it does not factor in the aspect that people can react differently to the same disease or treatment based on genetic differences. This is where personalized medicine aims to make a difference by factoring in genetic, environmental, and lifestyle differences.
Hereditary testing is one of the major shifts that occur in this new approach. By analyzing the DNA of an individual to determine what genetic mutations and gene differences an individual has, genetic testing enables the creation of risk profiles that can predict an individual’s susceptibility to disease many years before it occurs. This enables a doctor to tailor the screening time, preventive measures, and medications that will work best on an individual.
Genetic Insights Guide Risk Assessment and Early Detection
One of the first and most significant connections between genetic testing and personalized medicine is in the area of risk management. Many life-threatening illnesses, such as inherited cancers and cardiovascular diseases, are caused by specific genetic mutations. Genetic testing can assist in determining these mutations, which can then be used to develop a personalized risk management plan.
For instance, patients with genetic mutations that place them at risk for inherited cancer risk (such as BRCA1/2 for breast and ovarian cancer) can begin screenings earlier and more frequently than would be generally recommended. In addition, genetic testing can help identify patients with familial hypercholesterolemia, a genetic disorder that puts patients at a substantially increased risk for early heart disease, allowing for earlier lipid screenings and treatment.
With genetic risk assessment, doctors can begin treating patients before the disease even develops or progresses, making reactive medicine proactive.
Tailored Treatment Plans and Therapeutic Decisions
Apart from risk assessment, genetic testing is used in the treatment of diseases. In cancer treatment, genetic analysis of the tumor and genetic analysis of the patient’s genes can aid in the identification of certain mutations that are likely to respond favorably to certain treatments. Targeted therapies or drugs that target certain characteristics of a patient’s tumor have led to the successful treatment of diseases that were previously hard to treat.
In pharmacogenomics, genetic testing is used in the identification of how an individual’s genetic makeup affects the metabolism of drugs. Certain genes affect the metabolism of drugs in the body, and both efficacy and toxicity can be affected. With this information, a doctor can select the right drugs and dosage depending on the patient’s genetic makeup.
Supporting Preventive and Lifestyle Strategies
Personalized medicine not only involves treatment but also lifestyle and preventive medicine. Genetic data can encourage patients to change their lifestyle habits if they are aware of their genetic predispositions. For instance, patients with genetic predispositions to type 2 diabetes or cardiovascular disease can be offered personalized advice on how to counter their genetic predispositions.
This patient-centric approach synchronizes medical approaches with the patient’s biological context, thus improving patient engagement and compliance.
Advancing Healthcare Through Data Integration
With the increasing accuracy and cost-effectiveness of hereditary testing technologies such as next-generation sequencing (NGS), the use of such technologies in mainstream healthcare is slowly gaining momentum. Healthcare providers are increasingly using genetic information in electronic health records, which allow for the longitudinal analysis of genetic risk and the development of personalized decision support at the point of care.
The increasing use of hereditary testing is also a result of the increasing focus on data analytics, artificial intelligence, and bioinformatics, which allow healthcare providers to make sense of complex genetic information and use it to develop actionable healthcare plans.
Conclusion
The knowledge that is obtained from hereditary testing is the basis of the promise of personalized medicine. Hereditary testing is helpful in understanding genetic risk, treatment, and prevention, which are the elements that make it possible to practice personalized medicine, rather than the typical patient. As the market for hereditary testing continues to grow and become more incorporated into the practice of medicine, personalized medicine will become the norm.
