Many thanks to Gan Assurance and the Groupama Foundation
The donation requested by the association Les Extra-Vaillants MYT1L from the Groupama Foundation has two objectives:
1. The acquisition of an IPad 10 tablet and accessories for Les Vaillants (France) in order to :
Promote the development of alternative and augmented communication
Promote the development of learning
Promote the autonomy of people with MYT1L syndrome
The aim is to help families put in place more appropriate tools that are not covered by the MDPH or for which it still has to pay. A broader support fund is also a second objective.
=> For more information, contact: extravaillants@gmail.com
2. Welcoming and supervising families and Vaillants at the 2nd International Day for Families, Clinicians and Researchers on the MYT1L gene on 5, 6 and 7 JUNE 2025.

National Congress of the Rare Diseases Alliance 2023
The challenges of the 4th National Plan for Rare Diseases (PNMR)
GOING FURTHER
Since the launch of the PNMR3, strong measures have been taken to reduce the number of people with rare diseases who are left without a diagnosis.
These measures still need to be consolidated in a fourth national plan for rare diseases.
It will also be a question of using new measures to go even further in this area of diagnosis, as well as improving access to treatments for rare diseases and to biotherapies by reinforcing the collection of health data and biobanks.
(extract "Towards a fourth national plan for rare diseases (PNMR4): for greater synergies between care and research", Ministry of Higher Education and Research - 28/02/2023). You can consult the full press release with the assessment of the previous NRDPs by clicking on the underlined words.
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.
