Children’s Mercy Kansas City Pioneers Breakthrough in treating Rare Genetic Diseases with Personalized ASOs
In a groundbreaking development, Children’s Mercy Kansas City has revolutionized the treatment of rare genetic diseases through the use of personalized antisense oligonucleotides (ASOs). This innovative approach, detailed in a study published in Nature, has demonstrated remarkable success in preclinical evaluations, offering new hope for patients with previously untreatable conditions.
The study, titled Rapid and scalable personalized ASO screening in patient-derived organoids, highlights a method that significantly accelerates the process of generating patient-derived induced pluripotent stem cells (iPSCs). Traditionally, this process could take up to a year and cost between $5,000 and $10,000 per patient. However, the new technique requires onyl a small number of patient blood cells, reduces the timeline to just two to three weeks, and slashes costs to less than $500 per patient.
A Faster Path to Treatment
The research team utilized these iPSCs to grow patient-specific organoids, 3D cell models that mimic organ development and function. These organoids are invaluable for understanding disease biology and developing tailored therapeutics.“The team can generate iPSCs and organoid models for many patients in parallel, leading to an accelerated evaluation of therapeutic interventions,” explained Scott Younger, Ph.D., Director of Disease Gene Engineering at the Genomic Medicine Center and leader of The younger Laboratory at Children’s Mercy.
This streamlined process means families can go from a blood draw to a diagnosis or treatment proposal in just one to two months—a dramatic betterment over the previous timeline of over a year.
The Promise of Personalized ASOs
Personalized ASOs are short, synthetic strands of DNA or RNA designed to target specific genetic mutations. by leveraging patient-derived organoids, researchers can rapidly screen and identify the most effective asos for individual patients. This approach not only speeds up the development of treatments but also ensures they are highly tailored to each patient’s unique genetic makeup.
The implications of this breakthrough are profound. For families grappling with rare genetic diseases, the ability to access personalized therapies in a matter of weeks—rather than years—could be life-changing.

In a groundbreaking advancement, the Children’s Mercy Genomic Medicine Center has successfully validated a process using patient-derived organoids to treat Duchenne muscular dystrophy (DMD), a rare and debilitating genetic disorder. this innovative approach leverages antisense oligonucleotides (ASOs) to restore dystrophin protein expression and function, offering new hope for patients with this condition.
The study, conducted as part of the Genetic Answers for Kids (GA4K) program, utilized samples from three patients whose genetic variants were identified as suitable candidates for ASO therapy. For one patient, an FDA-approved ASO was used, while customized patient-specific ASOs were developed for the other two.The results were remarkable: dystrophin protein expression was successfully restored in the patient-derived organoids.
“Patient-derived organoid models have the potential to be widely used in creating cellular systems for investigating disorders involving the heart, kidney, liver, and other tissues,” said Steve Leeder, PharmD, Ph.D., interim executive director of the Children’s Mercy Research Institute. “They can also identify which medications are likely to be effective for a specific patient and which ones may not.”
This breakthrough is not just a scientific achievement but a paradigm shift in personalized medicine. By scaling the use of patient-derived organoid platforms, researchers aim to achieve a ‘bedside-to-bench-to-bedside-and-beyond’ approach, seamlessly integrating research with clinical care.
The implications of this study extend far beyond Duchenne muscular dystrophy. “The widespread ability to generate patient-derived cellular systems will have a substantial effect on the understanding of disease mechanisms as well as potential therapeutic avenues for the treatment of many rare diseases,” explained Dr. Younger.What makes this method particularly promising is its accessibility. “The methods and protocols generated in this study are accessible and can be implemented in any standard research laboratory without the need for specialized equipment or high-cost reagents,” Dr. Younger added.
The research team hopes that this approach will be adopted by institutions worldwide, enabling faster and more effective care for patients with rare diseases.

In a groundbreaking development, researchers have unveiled a novel approach to treating rare genetic diseases using patient-derived organoids. This innovative method, detailed in a recent study published in Nature, leverages antisense oligonucleotides (ASOs) to create personalized therapies tailored to individual patients. The research, led by John C. Means and his team, marks a significant leap forward in the fight against rare genetic disorders.
The Promise of Patient-Derived Organoids
Patient-derived organoids are miniature, three-dimensional structures grown from a patient’s own cells, mimicking the function of specific organs. These organoids serve as a powerful tool for testing potential treatments in a controlled surroundings.According to the study, this approach allows for rapid and scalable screening of ASOs, which are short strands of DNA or RNA designed to modulate gene expression.“This method enables us to identify the most effective ASO therapy for each patient quickly and efficiently,” said Means. The study highlights the potential of this technique to revolutionize the treatment of rare genetic diseases, which often lack effective therapies due to their complexity and variability.
A Breakthrough in Personalized Medicine
The research team focused on developing a personalized therapy pipeline that begins with creating organoids from patient cells. These organoids are then exposed to a library of ASOs to determine which ones correct the genetic defect. This process, described as rapid and scalable, significantly reduces the time and cost traditionally associated with developing personalized treatments.
The study’s findings, published in Nature, demonstrate the feasibility of this approach in addressing a range of rare genetic disorders.By using patient-derived organoids, researchers can bypass many of the challenges associated with traditional drug development, such as the need for extensive clinical trials.
Implications for Rare Genetic Diseases
Rare genetic diseases affect millions of people worldwide, yet many remain untreatable due to the lack of targeted therapies. The use of patient-derived organoids offers new hope for these patients, providing a pathway to personalized therapy that is both effective and accessible.
“This is a game-changer for patients with rare genetic diseases,” said a spokesperson from Children’s Mercy Kansas City, the institution that provided support for the research. “By tailoring treatments to the individual, we can improve outcomes and quality of life for those who have long been underserved by traditional medicine.”
