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.

1st day Families/Clinicians/Researchers around the MYT1L gene

November 25, 2022 - Rouen University Hospital

Highlighting the supports that made this incredible day possible

  • Financial donations, more than 6000 euros collected which have contributed in particular to bringing together and welcoming families in the same place in Rouen

  • Donations in kind for chocolate taste buds for young and old, toys for the treasure hunt of the children present, a warm and gourmet family drink, a salted butter caramel sweet to thank...

  • Gifts of skills to develop communication tools, to awaken to music, plastic arts and dance, to supervise children on D-Day...




Thank you so much !

Together we are super too strong!💪😉🧡

🔸 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.
