One of the most revolutionary developments in the field of preventive medicine has been hereditary testing. With the changing face of healthcare systems from a treatment-oriented approach to a risk management strategy, genetic knowledge is poised to play a pivotal role in the early diagnosis of diseases. Hereditary testing, through the analysis of inherited mutations in genes, helps assess the risk of serious diseases before the onset of symptoms.

Understanding Hereditary Testing
Hereditary testing is the process by which an individual’s DNA is analyzed for the presence of mutations that cause inherited disorders. Inherited disorders include cancers, cardiovascular diseases, neurological disorders, and metabolic disorders. Unlike other forms of testing, hereditary testing also includes the evaluation of genetic risk, which is very useful in the early stages of observation and prevention of diseases.
However, recent technological advancements in next-generation sequencing, polymerase chain reaction, and multi-gene panel testing have improved the sensitivity and efficiency of genetic testing. Consequently, hereditary testing is increasingly being applied in the fields of oncology, cardiology, reproductive medicine, and rare diseases.
In June 2023, Devyser Diagnostics AB, a Sweden-based diagnostics company, launched two new products: Devyser LynchFAP and Devyser BRCA PALB2. These targeted testing kits are intended for the screening of genes associated with an increased risk of cancer, such as those associated with Lynch syndrome and hereditary breast and ovarian cancers.

Early Detection: The Core Advantage
One of the most significant benefits of inherited testing is the ability to predict the risk of disease many years before the onset of symptoms. By detecting inherited genetic mutations at a young age, people can prepare for preventive strategies, regular monitoring, and prevent the possibility of rapid progression of the disease.
For example, inherited mutations in the BRCA1 and BRCA2 genes are known to cause inherited breast and ovarian cancers. Persons who test positive can consider the following options: early screening, MRI, preventive medications, and risk-reducing surgeries. Early detection provides an opportunity for survival and eliminates the risk of developing late-stage cancer.
Inherited genetic testing can also be used to assess the risk of developing some diseases, such as familial hypercholesterolemia, Lynch syndrome-related colorectal cancer, some neurodegenerative diseases, and some inherited metabolic disorders. Early diagnosis offers the chance to monitor and prevent the disease according to the genetic risk of the individual.
Family and Generational Impact
Since genetic mutations are passed down from generation to generation, hereditary testing has its advantages not only to the individual but also to the family as a whole. If one member of the family has a positive result for a pathogenic variant, other members can be tested for targeted results.
For couples who are planning to have children, hereditary carrier screening can determine the risk of passing on genetic diseases to offspring.
Market Growth and Adoption Trends
The increasing awareness about preventive healthcare, the increasing number of cases related to genetic disorders, and the decreasing cost of sequencing are fueling the growth of the hereditary testing market. The acceptance of direct-to-consumer testing, the application of artificial intelligence in genomic analysis, and the government initiatives for early diagnosis are also accelerating the growth.
Healthcare professionals are increasingly offering genetic counseling services and hereditary testing to ensure that patients are well-informed about the results of the test. Reimbursement policies are expanding, and advancements in genomic technology are expected to make hereditary testing a routine part of primary healthcare.
Final Thoughts
Hereditary testing is giving a new meaning to "early risk prediction" for diseases by using genetic knowledge to create effective healthcare strategies. This is very beneficial in taking preventive measures by understanding risks before the onset of the disease, thus ensuring better health outcomes.
The hereditary testing market is expected to play a pivotal role in creating a predictive, preventive, and patient-centric healthcare system with the advancements in the field of genomic science.
