Explain for a better understanding
To support the meeting with schoolchildren, we have produced a video explaining the syndrome, its effects, rare diseases and the association.
This is the version for middle-school students; a simplified version is available on request for schoolchildren.

📍 REMINDER
1st International Day Families, Clinicians, Researchers around
the MYT1L gene
We were 99 present at the Rouen University Hospital: children, students, families, professionals, speakers, organizers!
We were nearly 60 connected via ZOOM at the height of the day
We will be even more connected to the Replays soon available
All our sincere, enormous thanks to all the speakers of this incredible day, to the reference center for developmental anomalies of the ROUEN University Hospital, to the AndDI-Rares health sector, to the artists, to the students, to our donors (in kind, skills, financial support).
To you strangers, families, friends, association, agency, company, hotelier, entrepreneurs....
A special thought for Dr Juliette Coursimault, Anne-Marie Guérrot, François Lecoquierre and for Gwendoline Giot.
Here are some images ... many more on our YouTube channel

Article by the team of the Clinical Genetics Unit of the CHU from Rouen whose Dr Juliette Coursimault, Dr Ann e-Marie Guerrot and Dr François Lecoquierre.
Journal Human Genetics - November 8, 2021
In-depth clinical and biological characterization of the haploinsu isance of the MYT1L gene. Literature review and description of a new cohort of 40 patients
Arcticle from Bettina Weigel, Jana F. Tegethoff, Moritz Mall, and their team, for their important work presenting the “first evidence” that MYT1L mutations alter neuronal cell fate and function, and for demonstrating that a drug commonly used for epilepsy can reverse ASD -associated phenotypes in mice and #electrophysiological abnormalities in vitro. Nature, February 2023
MYT1L haploinsufficiency in human neurons and mice causes autism-associated phenotypes that can be reversed by genetic and pharmacologic intervention.
📣 NEW

This study highlights the interesting effect of a molecule called Lamotrigine on the behavior of mice with an anomaly in the MYT1L gene. Please note that therapeutic trials have only been carried out 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 Dr. Mall's team. We should know more by summer (feasibility, cschedule, 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.
