HEIDELBERG, GERMANY JUNE 2025, MYT1L GENE MINI SYMPOSIUM
It was a great pleasure and honor for Les Extra-Vaillants MYT1L to take part in a dedicated mini-symposium on MYT1L syndrome on June 26th, during the 4th Triennial Meeting of the International Alliance of Academies of Childhood Disability (IAACD) and the 37th Annual Meeting of the European Academy of Childhood Disability (EACD), held in Heidelberg, Germany, from June 24th to 28th, 2025.
We were invited by the symposium chairs, Prof. Dr. Maja Hempel, Head of the Genetic Outpatient Clinic at University Hospital Heidelberg, Germany, and Dr. Moritz Mall, Research Group Leader at the Hector Institute for Translational Brain Research at the German Cancer Research Center, and joined by Dr. Juliette Coursimault, Clinical Geneticist at CHU Rouen.
We were also delighted to reconnect with Dr. Jorge Granadillo, Medical Geneticist at Washington University School of Medicine in St. Louis, USA, who had joined us just a few weeks earlier for the 2nd MYT1L Family–Clinician–Researcher Meeting held in early June 2025 in Rouen.
June 26th was a day rich in discussions, discoveries, and plans for collaboration.
We had the opportunity to meet the teams of Dr. Moritz Mall and Prof. Maja Hempel in their respective units at the Heidelberg Clinic. On the agenda: a tour of the genetics department and research laboratories, exchanges with the teams, discussions on potential projects, and a virtual meeting with several German families.
The day ended on a warm and friendly note over a shared meal.
Thank you for your hospitality and for these essential moments!
Long live collaboration and Franco-German friendship! 🇫🇷🇩🇪
It was also a great pleasure to attend the conference sessions in the following days and to witness the international medical community’s commitment to improving the lives of patients. Many thanks to the organizers for their kind invitation.

Collaboration with Dr. Moritz Mall teams
On February 14, 2023, Dr. Moritz Mall and his collaborators published:
"MYT1L haploinsufficiency in human neurons and mice causes autism-associated phenotypes that can be reversed by genetic and pharmacologic intervention”.
This publication highlights the interesting effect of a molecule called Lamotrigine on the behavior of mice with an anomaly in the MYT1L gene. Please note, for this study, the therapeutic trials were carried out only in mice. There are still many steps to know if it could work in humans.
The existence of the drug on the market, its already effective use in neurology and psychiatry are important factors that will save time in the study projects of the passage from mouse to human in order to define the real effectiveness. , necessary dosage and side effects for MYT1L patients.
It is likely that a new study will soon see the light of day, led by the team of Dr Mall (Germany) We should know more by the summer (feasibility, schedule, cost, coordination with the geneticists of Rouen and the 'association...). This opportunity should accelerate the clinical study on the behavioral disorders we have been talking about since the beginning of our collaboration with Dr. Coursimault and Dr. Guerrot.
TO GO FURTHER
Dr. Moritz Mall, of theHector Institutefor Translational Brain Research (HITBR), has long studied the role of the protein MYT1L in various neuronal diseases. He had agreed to answer questions from Jonte's parents about MYT1L syndrome. You will find the link of thisinterview translated into French on the German family page(click on the underlined words).
Mr. Mall has been conducting basic research on the MYT1L gene since 2012 and has had his own research group in Heidelberg since 2018.
📣📍COMPLEMENTARY DRAFT DESCRIPTION OF EATING DISORDERS LINKED TO THE GENE MYT1L
🔸 We have the great pleasure of relaying the information of the geneticists Dr Coursimault and Dr Guerrot of the reference center for developmental anomalies and malformation syndromes of the University Hospital of Rouen, concerning the complementary project of description of eating disorders linked to the geneMYT1L, which is part of the follow-up to the clinical-biological study carried out in 2020.
🔸 This project is a collaboration between the reference center for developmental anomalies and malformation syndromes of the Rouen University Hospital, and two professors, Pr Poitou Bernert and Pr Dubern, endocrinologists specialized in genetic obesity in adults and children. , respectively, practicing at the Pitié Salpêtrière Hospital and at the Trousseau Hospital and belonging to the PRADORT Reference Center for Rare Diseases. 🔸
For the moment, this is a project that only targets patients with an eating disorder, ie an eating disorder, or overweight, or obesity.
🔸 To carry out this project, your genetic doctors will contact you to present the project to you. For children, these are questionnaires to be completed by parents. For adult patients, help from a nearby adult may be needed. Then, you will have to retransmit these completed questionnaires to your geneticist, who will be responsible for transmitting the data to the Rouen team.
📍📍 If you are not asked and your child is affected by this issue, do not hesitate to contact your geneticist, or contact us: extravaillants@gmail.com to provide you with a solution.
👍 Another step in favor of all the Valiants to better understand, improve trajectories!
👍 Thank you to the doctors who are mobilizing with us around the geneMYT1L.
