For every rare mutation, there is an extraordinary child
EIF3F-related neurodevelopmental disorder is characterized by intellectual disability, sensorineural hearing loss, epilepsy, behavioral problems, and various physical abnormalities including short stature and microcephaly.
All our patients are homozygous for c.694T>G/p.(Phe232Val) in EIF3F.
Beside variable intellectual disability in all individuals, epilepsy occurs for majority of them, as well as behavioral problems or sensorineural hearing loss in some cases, respectively.

5- years old boy, Nowy Sącz.

The non-profit organization dedicated to drive treatment development for ultra-rare neurodevelopmental disorder (OMIM #618,295: intellectual developmental disorder, autosomal recessive 67) caused by mutation in EIF3F gene.
Our aim is to improve the quality of life for affected patients and their families. We anchor our efforts on interdisciplinary and international cooperation, building and fortifying patient-scientists-clinicians partnership and sharing experience with other research foundations.
Privately we are Anna and Tomasz – parents of Hanna who is impacted by the mutation.
The foundation is registered in Kraków, Poland, however we aim to operate worldwide for all patients affected by the disorder.
Our patients from Poland are under the supervision of Jagiellonian Medical University – Collegium Medicum in collaboration with other genetics in the country.
This is the foundation of our work. Continuous clinical care and collaboration with Polish geneticists allow us to collect crucial data and provide patient support, which is the starting point for all international research projects.

In May 2024, we reached a milestone: we created two IPSC cell lines. These cells, produced by iXCells Biotechnologies, are a key tool for modeling disease in the laboratory and testing potential therapeutics.
We have partnered with Everlume Bio to assess the disease's susceptibility to various types of therapy. Our next planned steps include creating a mouse model, CRISPR mutagenesis, and developing specific research assays.
We're open to collaboration! We're actively seeking researchers and institutes who want to help us create fibroblasts, brain organoids, and drug repurposing research.
