Medications to restore RAI1 in Smith-Magenis syndrome
Therapeutics that Correct the Underlying Cause of Smith-Magenis Syndrome (SMS)
This project explores medicines that might raise RAI1 levels to help children and teens with Smith-Magenis syndrome.

What this research studies
Researchers are testing a small library of compounds chosen because they increase RAI1 (RAI1) expression. They will use lab assays and animal models to see whether these compounds raise RAI1 and correct the downstream gene-expression changes caused by the RAI1 deletion. The team aims to show a pharmacologic approach can fix many of the transcriptomic defects linked to SMS. If the lab results are promising, these findings could guide the development of future treatments for people with SMS.
Who could benefit from this research
Good fit: This work is aimed at people with Smith-Magenis syndrome caused by a deletion or loss of one RAI1 allele, particularly children and adolescents who typically show symptoms.
Not a fit: People whose symptoms are caused by conditions unrelated to RAI1 loss, or those without SMS, are unlikely to benefit from these specific compounds.
Why it matters
Potential benefit: If successful, this work could lead to drugs that restore RAI1 activity and improve neurodevelopmental symptoms in people with Smith-Magenis syndrome.
How similar studies have performed: This is early preclinical work; some gene-boosting approaches have shown promise in lab models but have had limited translation to people so far.
