This study reveals SYNGAP1 expression and function in radial glia before synaptogenesis, contradicting its classification as purely a synaptic protein. The molecular mechanisms underlying this non-synaptic role remain unexplained, which is critical for understanding ASD pathophysiology.

SYNGAP1 haploinsufficiency in GABAergic interneurons causes circuit-level dysfunction by impairing developmental assembly rather than solely mature synaptic transmission.
Dimension Scores
How to read this chart:
Each hypothesis is scored across 10 dimensions that determine scientific merit and therapeutic potential.
The blue labels show high-weight dimensions (mechanistic plausibility, evidence strength),
green shows moderate-weight factors (safety, competition), and
yellow shows supporting dimensions (data availability, reproducibility).
Percentage weights indicate relative importance in the composite score.
