  • An Introduction to the Technologies Transforming Precision Medicine



    In recent years, precision medicine has become a major focus for researchers and healthcare professionals. This approach offers personalized treatment and wellness plans by utilizing insights from each person's unique biology and lifestyle to deliver more effective care. Its advancement relies on innovative technologies that enable a deeper understanding of individual variability. In a joint documentary with our colleagues at Biocompare, we examined the foundational principles of precision medicine and the tools that make it possible.

    An Introduction to Precision Medicine
    The film begins with a comprehensive introduction to precision medicine, featuring interviews with leading experts such as Sharon Terry, Leroy Hood, Michael Snyder, and Courtney Noah. These experts share how precision medicine is often associated with disease treatment, but it also includes the development of optimized wellness plans. This strategy combines data from diverse fields like genomics, metabolomics, and various biomedical data sciences. At its core, precision medicine is about personalizing healthcare and moving beyond the traditional one-size-fits-all approach. This philosophy highlights a growing realization in healthcare that contemporary biology is far too complex for universal solutions. Put simply, precision medicine ensures that treatments and wellness plans are as unique as the individuals receiving them.

    The Impact of Precision Medicine
    Precision medicine is often framed as a distant vision rather than a present reality. However, precision medicine is already being applied and actively changing lives. During the film, Michael Snyder recounted how sequencing his genome revealed a high risk for type 2 diabetes, a diagnosis that might have otherwise gone unnoticed. This allowed him to prepare better and adopt lifestyle changes to manage his condition effectively. Snyder emphasized the importance of these insights, enabling earlier intervention and better disease management.

    Similarly, Sharon Terry shared her experience of dealing with a rare genetic disease in her children. At the time, the disease was relatively unknown, and no research was being conducted to understand it. This motivated Terry and her husband to initiate their own research efforts, which led to the discovery of the causative gene, the development of a diagnostic test, and the formation of a research consortium to determine how to treat this condition.

    These stories of a parent’s mission to identify their child’s rare genetic disorder and a researcher’s discovery of their genetic predisposition to diabetes exemplify the impact and necessity of precision medicine on individual lives.

    Importance of Diversity and Inclusion
    Another critical aspect of precision medicine is the importance of diversity in translational research and clinical trials driving the field. Historically, certain populations such as African Americans, Asians, and Latinos have been excluded from studies, hindering efforts to identify genetic markers relevant to these groups. To address this disparity, researchers must build more inclusive clinical trial designs and diverse biospecimen collections. As emphasized in the film, understanding individual differences is essential for identifying the factors that influence health and disease. This will lead to improved treatments, prevention strategies, and diagnostic tools for everyone. While efforts to promote inclusivity are gaining momentum, significant work remains to provide a more effective and equitable healthcare system.

    Technologies Enabling Precision Medicine
    Among the diverse components of precision medicine, this documentary focuses on the technologies driving its advancement. These technologies are key components of foundational research and clinical workflows, providing the essential insights needed to identify the important differences between individuals. The film features important technologies which include next-generation sequencing (NGS), flow cytometry, organoids, spatial technologies, and essential tools for antibody discovery. Each segment discusses a vital technology, how it is being applied, and how it is enhancing the precision medicine workflow, highlighting how each of these tools works together to create a comprehensive approach for a more personalized healthcare solution.

    Next-Generation Sequencing
    The first technology highlighted in the film is NGS. After its introduction in the mid-2000s, NGS allowed researchers to decode vast amounts of genetic material in a single run. As many in the SEQanswers community are aware, this tool has forever transformed the way scientists investigate genomes, transcriptomes, epigenomes, and now even proteomes. Within precision medicine, NGS is used to identify disease-related genetic variants, assess a patient’s predisposition to certain conditions, and predict responses to therapies.

    Impact of NGS
    Cancer, like many diseases, is fundamentally a genetic condition. Whether inherited or acquired, genetic mutations play a central role, and sequencing tumor DNA helps us identify those mutations to guide treatment. This approach can be used for early detection or to select therapies that target specific mutations. NGS has been adopted by institutions like Rady Children’s Institute for Genomic Medicine to diagnose rare diseases in children. Normally, it takes many genetic tests and several years to obtain an accurate diagnosis. Advances in sequencing accuracy and speed have made it possible to diagnose within a day, as well as address previously undiagnosed cases. NGS provides families with answers and clinicians with the tools to deliver precision care.

    Advances in NGS
    Over the years, NGS has seen significant advancements that include a sharp decline in costs and a substantial increase in speed, accuracy, and read lengths. Recent developments include single-cell sequencing, which has enabled researchers to take snapshots of individual cellular behavior and interactions. The integration of artificial intelligence is another major development in the field. AI has accelerated data analysis and provided insights into disease-causing variants that might be missed with traditional analysis methods. NGS is also a major component of most multiomic workflows. The combination of genome sequencing with other approaches like spatial technologies provides deeper insights for a comprehensive view of health.

    Additional Technologies
    NGS is just the beginning of the suite of essential technologies that drive precision medicine. Each plays an important role in uncovering biological insights and advancing personalized care. Upcoming segments will explore how spatial biology provides context for cellular interactions within their native environments, and how organoids serve as powerful models for studying disease and testing therapies. We’ll also examine the role of flow cytometry in characterizing cell populations and the importance of antibody discovery technologies in developing targeted treatments. Together, these tools create an integrated workflow that is improving how we approach precision medicine.
