FBXO28 Research Foundation
Accelerating Research for FBXO28 Disorders
Building an international scientific programme to understand FBXO28 biology and accelerate the development of future therapies.

Building the Foundation for Future Therapies
From the very beginning, our goal has been to build the scientific infrastructure needed to accelerate FBXO28 research. By developing patient-derived biological resources, fostering international collaborations and supporting cutting-edge disease modelling, we aim to create the foundation for future therapeutic discovery.

About FBXO28
FBXO28 is a gene involved in the ubiquitin–proteasome system, an essential pathway that regulates proteins within cells. It plays an important role in brain development and neuronal function.
Disease-causing variants in FBXO28 are associated with Developmental and Epileptic Encephalopathy 100 (DEE100), an ultra-rare neurodevelopmental disorder.
Clinical features may include:
- Developmental delay
- Intellectual disability
- Hypotonia
- Epilepsy or infantile spasms
- Feeding difficulties
- Movement disorders
- Visual impairment, including possible cortical visual impairment
- Autism spectrum features
There are currently no disease-modifying therapies. Understanding the underlying biology is therefore the essential first step toward developing effective treatments.
Because FBXO28 participates in fundamental cellular pathways, discoveries made through FBXO28 research may also contribute to oncology, neurodegeneration and precision medicine.

Research Programme
A staged programme moving from understanding disease biology toward future therapeutic development.
01
Disease Mechanisms
Study how FBXO28 variants alter cellular pathways and neuronal function.
02
Patient-derived Cellular Models
Expand fibroblast and iPSC resources and develop disease-relevant cellular models.
03
Multi-omics
Generate transcriptomic and proteomic datasets to identify disrupted pathways and biomarkers.
04
Drug Repurposing
Develop phenotypic screening approaches for existing compounds and therapeutic candidates.
05
Future Therapeutic Development
Translate validated discoveries into longer-term therapeutic strategies.
For Researchers
The Foundation actively welcomes collaborations with academic laboratories, clinicians and biotechnology partners. Our goal is to remove barriers to rare disease research by providing access to patient-derived biological material, clinical documentation and an expanding international research network.
Research resources
- Patient-derived fibroblasts – available
- Patient-derived iPSC resources – available and expanding
- Clinical phenotype documentation
- Longitudinal follow-up
- Future transcriptomic and proteomic datasets

About the Foundation

About the Founder
The FBXO28 Research Foundation was founded by Aleksandra Sułkowska-Bojarczyk, MD, first and foremost the mother of Klara, a child diagnosed with an ultra-rare FBXO28-related disorder.
Faced with the uncertainty that accompanies an ultra-rare diagnosis, Aleksandra and her husband, Sergiusz, made a family commitment to build an international network of scientists, clinicians and research partners dedicated to accelerating FBXO28 research and the development of future therapies.
Although Klara’s diagnosis was the catalyst for this work, the Foundation was created for the entire global FBXO28 community, with the goal of advancing research, fostering collaboration and helping bring effective therapies closer to patients.
