Researchers from the BRAINmodel consortium and colleagues from Belgium are preparing to participate in the European satellite event of the 2024 Million Dollar Bike Ride. The ride, orchestrated by the Orphan Disease Center in Philadelphia, aims to generate funds earmarked for critical rare disease research grants, with our teams’ funds specifically dedicated to STXBP1 studies.

Scheduled for Saturday, June 8th, the race will see both teams embarking on an 80-kilometre journey to a designated midpoint between Antwerp and Amsterdam.

Building upon the success of the 2022 event, where over 10,000 euros were raised, we aspire to make this year’s race an even greater triumph.

Your support is paramount in our quest. Kindly consider contributing through the following link:

On June 1th-June 2^nd, the European Joint Program together with Prof. Tjitske Kleefstra, is organizing a Kleefstra Syndrome Scientific conference in Ljubljana. This event is open for everyone and free of charge for online participants.

“The Kleefstra Syndrome Scientific Conference 2023: “Moving towards the uptake and use of Artificial Intelligence (AI) in research and clinical work” focuses on Kleefstra syndrome, a rare genetic disorder with app. 1000 diagnosed patients worldwide. Due to the rarity of the disease, a global perspective is needed to foster new research insights. The event brings together Kleefstra syndrome PAOs, clinicians and researchers from different domains having a common interest: share new research findings related to Kleefstra syndrome that will lead the Kleefstra community to optimize current care and to reach their final goal, the discovering of a life-changing treatment and cure for Kleefstra syndrome. A special focus is given to artificial intelligence (AI), which is generally still something new for the rare disease communities, but it can play a crucial role, especially in shortening the time needed for new research insights.” (https://idefine-europe.org/conference/)

Op 1 t/m 2 juni organiseert het European Joint Programme samen met prof. dr. Tjitske Kleefstra een Kleefstra Syndrome Scientific congres in Ljubljana. Dit evenement is voor iedereen toegankelijk en gratis voor online deelnemers.

“The Kleefstra Syndrome Scientific Conference 2023: “Moving into the uptake and use of Artificial Intelligence (AI) in research and clinical work” richt zich op het Kleefstra-syndroom, een zeldzame genetische aandoening met ongeveer 1000 gediagnosticeerde patiënten wereldwijd. Vanwege de zeldzaamheid van de ziekte is een mondiaal perspectief nodig om nieuwe onderzoeksinzichten te bevorderen. Het evenement brengt clinici en onderzoekers uit verschillende domeinen samen met een gemeenschappelijke interesse: nieuwe onderzoeksresultaten met betrekking tot het Kleefstra-syndroom delen die de Kleefstra-gemeenschap ertoe zullen aanzetten de huidige zorg te optimaliseren en hun uiteindelijke doel te bereiken: het ontdekken van een behandeling en genezing van het Kleefstra syndroom. Er wordt speciale aandacht besteed aan kunstmatige intelligentie (AI), wat een cruciale rol kan gaan spelen, vooral bij het verkorten van de tijd die nodig is voor het genereren van nieuwe onderzoeksinzichten.” (https://idefine-europe.org/conference/)

Within the BRAINmodel project we aim to link clinical outcome measures in patients with brain disorders to abnormal cellular functions in material (iPSC-derived neurons) from these same patients. To do this, we need to prepare many aspects of the project, and in the last months we have made significant progress which we would like to share with you.

Our research protocol has been approved by the ethics committee and also by the boards of directors of both Amsterdam UMC and Radboudumc! An important step before we could start our study.

At this moment we are recruiting participants for the BRAINmodel study. We are very happy to share that we have already included nine children in our research. We will carefully map out their medical problems, behaviour, metabolism and potential issues with their immune system. We will also perform an EEG recording to measure their brain activity. For a subset of patients we will combine this with research on the patient’s own stem cells, grown into functional neurons within the lab. With this, we hope to gain a better understanding of stimulus processing and the balance between over- and under-stimulation.

Last week we tested our EEG equipment at Radboudumc. And it works! That is why we are now completely ready to meet the first patients for BRAINmodel.

BRAINmodel PhD student Sietske van Till (Erasmus MC) has published an article in the magazine ZeldSamen about her research towards the ethical implications of the use of stem cells to study neurodevelopmental disorders. ZeldSamen is a dutch patient organization offering information, contact and recognition for parents after the diagnosis of a rare genetic syndrome. They collaborate within the BRAINmodel project as stakeholders.

To gain more insight in parents’ overall experiences and their moral perspectives on stem cell research, Sietske van Till and Dr. Eline Bunnik started an interview study among parents of children with the Kleefstra-syndrome or an STXBP1 mutation. In her article, Sietske explains more about the BRAINmodel study, the interviews and how to participate in this research.

Starting 2023, we will initiate the clinical research workpackages within the BRAINmodel project, in which multiple children with SNAREopathies or Chromatinopathies will be investigated, see also our flyer. If you are interested in participating, please contact [email protected].

We bike together to raise money for research towards new treatments for the rare disorder STXBP1 Encephalopathy!

We will raise money for rare disease research on Saturday, June 11, 2022, as European counterpart of The Million Dollar Bike Ride organized by the Orphan Disease Center in the US.

Researchers working on STXBP1 encephalopathy from the VU University and Amsterdam UMC (Netherlands) and University of Antwerp and Antwerp University Hospital (Belgium) will bike towards a halfway point between their labs in Amsterdam and Antwerp. With this combined 170 kilometer bike ride, we hope to raise as much money as possible to aim for a better future for patients suffering from rare disorders. All donations will be transferred to the STXBP1 team of The Million Dollar Bike Ride campaign of the Orphan Disease Center, which supports research towards new treatments for rare disorders.

Please donate here.

If you are interested in riding along with us, or would like to join us at the middle point, please contact us at [email protected].

STXBP1 Encephalopathy
STXBP1 Encephalopathy is a severe genetic disease caused by a disease causing variant in the STXBP1 gene. STXBP1-E patients show a developmental delay in their first years, typically resulting in intellectual disability at a later age. Epilepsy is a common symptom (89% of patients) and is difficult to treat. Many patients also suffer from additional symptoms, such as movement disorders (e.g. muscle hypotonia, ataxia) or neuropsychiatric features such as autism spectrum disorder. The severity of the disorder differs between patients, and until now there is no disease-modulating treatment available.
We, researchers at the Vrije Universiteit (VU) Amsterdam and the Amsterdam UMC, the Netherlands, as well as the VIB Center for Molecular Neurology at the University of Antwerp and Antwerp University Hospital, Belgium, work together to better understand STXBP1- Encephalopathy. We aim to improve diagnosis and therapeutic interventions, and study the disease to understand how mutations in STXBP1 lead to STXBP1 encephalopathy. For more information on the disorder and our research, visit our websites stxbp1.cncr.nl and Sarah Weckhysen lab .

The first results of the BRAINmodel consortium have been published as a concept paper in the scientific magazine Genes. This is a flying start for the consortium, which just started a few months ago, and it is great to see the recognition of our work and plans by the scientific community.

In the paper ‘Following Excitation/Inhibition Ratio Homeostasis from Synapse to EEG in Monogenetic Neurodevelopmental Disorders’ we present our strategy to integrate multiple levels of neuroscientific investigations to develop personalized treatment strategies in patients with neurodevelopmental disorders. We focus on excitation/inhibition ratio homeostasis across cellular and in-patient measurements in patients with chromatin- and SNAREopathies.
