Language, speech, prosody and cognitive profile in people with MYT1L syndrome

Characterisation of Language and Prosody Disorders, Cognitive Functioning and Behavioural Problems in MYT1L Syndrome

Observational University Hospital, Rouen · NCT07008612

This project will test a standard battery of language, speech, prosody and cognitive tests in French-speaking children and adults with MYT1L syndrome to define their communication and neuropsychological profile.

What this trial studies

This is an observational, clinic-based project that uses a routine-care protocol to collect standardized neuropsychological, speech and prosody measures in patients with molecularly confirmed MYT1L syndrome. Participants undergo tests of oral language, speech production, prosodic reception and expression, global IQ, executive function, attention, sensory profile and mood/behavior. The aim is to identify a reproducible language, prosodic and cognitive-behavioral profile that can guide screening and more targeted rehabilitation. The protocol is offered at the University Hospital of Rouen and focuses on French-speaking patients aged six years and older.

Who should consider this trial

Good fit: Ideal candidates are French-speaking patients aged six years or older with a molecularly confirmed MYT1L-related neurodevelopmental disorder and parental or guardian consent.

Not a fit: Patients unlikely to benefit include those under six, non-French-speaking individuals, those with unaided vision or hearing loss that prevents testing, people with a second molecular diagnosis causing neurodevelopmental disorder, nonverbal patients for the prosody arm, or those with acquired neurological disorders.

Why it matters

Potential benefit: If successful, the results could help clinicians recognise MYT1L-specific language and behavioral patterns, improve early screening, and better target rehabilitation approaches.

How similar studies have performed: Prior work by this team described 40 individuals worldwide and confirmed universal neurodevelopmental features in MYT1L patients, but no previous study has prospectively standardized neuropsychological, language and prosody profiling, making this effort largely novel.
