Thank you to Alice, Clémence and Neïa our MYT1L Extra-Vaillants ambassadors!

Thank you to friends and family for being there with us for this very special moment! There were over twenty of us!

Well done Clémence for braving all the weather and making it to the end of the walk! You look magnificent with the Eiffel Tower behind you.

Bravo Neïa for being so strong and proud to hold the Vaillants sign for this walk, you're so cute.

Bravo Alice for taking the march all the way to the metro and the trunk of your car! We'll keep talking about the march in Rouen.

To all you Vaillants, we've been thinking of you!

Thank you Alliance Maladies Rares.

It was an intense day! A 1st Cross Solidaire for the association and the 12th for the Sacré Coeur and Ange Gardien schools and college in Domfront!
It will remain a vibrant memory and a support that will benefit Les Vaillants for a long time to come.

It was a moment of sharing, commitment, kindness and crazy warmth!
We formed a whole around the Vaillants, and their three little representatives of the day, Neia, Elsa and Alice.

Neia's family is originally from the region, so she was incredible! Thank you 🧡💛💙

They've done it!
They did the incredible!!!

When children mobilize to help other children with special needs...

❤️ This is huge! Thanks from the Vaillants!

We owe this wonderful opportunity to a young lady by the name of Azéline, who rallied round on behalf of her little cousin and all the Vaillants.

She introduced the association to her classmates as part of a school project, and lobbied for us to be the lucky beneficiaries of this year's CROSS SOLIDAIRE for her school and associated elementary schools - Sacré Coeur, Ange gardien and Collège du Sacré Coeur de Domfront.

A huge, huge thank you to Azéline and all the students and their teachers for this outpouring of their hearts, which means so much to us! Every year they mobilize, and you can find out more about their actions here :

We had the great pleasure of meeting and talking with the students on Friday 22/09/23.

Here are a few images, a publication and a VIDEO presenting the pathology and the association to the schoolchildren (simplified video for school level available on request).

National Congress of the Rare Diseases Alliance 2023

The challenges of the 4th National Plan for Rare Diseases (PNMR)

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.

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.

🔸 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: 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.

Thanks to the AnDDI-Rares health sector and Unapei,  we followed a two-day training course on the design of communication tools in Easy to Read and Understand - FALC.

Two days led by Hugo, enriching and productive, with health professionals and associations. It was fun and stimulating!

We continue the work started and prepare tools for children .  A little more patience….

College of France - May 31, 2022

We had the pleasure of attending this symposium where medical and health sciences rubbed shoulders with human and social sciences.

Needless to say that it was rich!

We invite you to connect to the YouTube channel of the Rare Disease Foundation for a replay of topics that may interest you (reminder of the program ).

Following the issues raised by certain families, we are giving you more specific information on an article on the complexity of patient follow-up in the transition from pediatrics to "adult" follow-up:

- " Between medical transition and passage to adulthood, a possible conflict of temporality for young people with a chronic disease "
