Transposon insertions represent a significant yet understudied source of disease-causing variants and therapeutic targets. Through transposon profiling on patient cohorts with rare diseases, we uncovered a diverse collection of pathogenic insertions, including inherited, de novo, and mosaic events, many disrupting RNA splicing. In addition to molecular diagnosis, this talk will showcase the journey from the discovery to the design, development, and deployment of a tailored ASO therapy for a child with progressive vision loss caused by one such splice-altering transposon insertion.
Dr. Boxun Zhao obtained his PhD in Genetics in 2017 from Peking Union Medical College and Tsinghua University in China. As a Postdoctoral Research Fellow jointly mentored by Drs. Timothy W. Yu and E. Alice Lee at Boston Children’s Hospital, his research interests encompass basic research, molecular diagnosis, and genomic medicine, with a specific focus on transposons ("jumping genes") in the human genome. To improve the diagnosis and treatment of rare genetic diseases, Dr. Zhao has developed innovative sequencing methodologies and analytical pipelines for the detection of inherited, de novo, and somatic mutations for genetic cases. His background in transposon biology, coupled with his experimental and computational proficiency, provides a strong foundation for his long-term goal of resolving the importance and functional impact of transposon insertions in human diseases; and translating scientific discoveries into therapeutics.
My husband was diagnosed with Creutzfeldt-Jakob Disease (CJD) four years ago. For over two years, we relied on prescription medications and therapies, but unfortunately, his symptoms continued to worsen. His memory, coordination, and overall strength declined, and everyday life became increasingly difficult.Last year, out of desperation and hope, we decided to try an herbal treatment program from NaturePath Herbal Clinic. Honestly, we were skeptical at first, but within a few months of starting the treatment, we began to notice real changes. His alertness improved, his movements became steadier, and he regained a surprising amount of energy and clarity.Incredibly, he also regained much of his independence and confidence. It’s been a life-changing experience he feels more like himself again, better than…
