What this research studies

From a patient's perspective, this project uses human cell models to study RHOBTB2 gene variants found in people with developmental and epileptic encephalopathy (RHOBTB2-DEE). Researchers will compare normal and mutant RHOBTB2 proteins to see if the mutant proteins are more stable or interfere with the healthy protein. They will examine the molecular and cellular effects of the most common disease-causing variants to understand how brain cells are disrupted. The work aims to identify mechanisms that could be targeted by future therapies.

Who could benefit from this research

Good fit: Ideal candidates for any sample donation or future trials would be children or families with a confirmed pathogenic RHOBTB2 variant and a diagnosis of RHOBTB2-related developmental and epileptic encephalopathy.

Not a fit: Patients whose epilepsy is caused by other genes, non-genetic causes, or who do not carry RHOBTB2 variants are unlikely to benefit directly from this project's findings.

Why it matters

Potential benefit: If successful, the work could reveal molecular targets for therapies that reduce seizures and improve development in children with RHOBTB2-DEE.

How similar studies have performed: This approach is largely novel for RHOBTB2, although similar gene-focused lab studies have helped lead to treatments for other genetic developmental and epileptic encephalopathies.
