Roadmap to advance therapeutics for SYNGAP1-related disorder: a patient organization perspective from SynGAP Research Fund.

SYNGAP1-related disorder (SRD) is a developmental and epileptic encephalopathy caused by a disruption of the SYNGAP1 gene. At the beginning of 2024, it is one of many rare monogenic brain disorders without disease-modifying treatments, but that is changing. This article chronicles the last 5 years, beginning when treatments for SRD were not publicly in development, to the start of 2024 when many SRD-specific treatments are advancing. We discuss the progress across many realms that have brought SRD to the forefront of drug development and highlight how Patient Advocacy Groups (PAGs) have had direct roles in accelerating the route to meaningful treatments for our children. We start with a summary of why SRD is an attractive pharmaceutical target. Second, we introduce the disease, the clinical features, and the number of patients. Next, we describe our PAG, our international partners and cite examples of the broad range of activities we believe are accelerating our pace toward treatments. We summarize the current SYNGAP1 pipeline and the status of each public project. Finally, we discuss two open questions that urgently need to be addressed in advance of clinical trials for SRD.
