Intellectual Disabilities and Autism

In August, 2024 study, researchers suggest that accelerated brain development may contribute to intellectual disabilities and autism.

Key Points

Gene Role: A gene called SYNGAP1 typically supports prolonged brain cell development, which is crucial for advanced cognitive functions in humans.
Disruption Findings: Mutations in SYNGAP1 disrupt this extended developmental process, potentially leading to intellectual disabilities and autism.
Research Methodology: Scientists at the Flemish Institute for Biotechnology transplanted human neurons with mutated SYNGAP1 into mice brains, observing their development and functionality.
Accelerated Development: The study found that mutated neurons developed significantly faster, integrating with other neurons more quickly and responding to visual stimuli earlier than normal.
Implications: These findings shed light on the effects of SYNGAP1 mutations and could inform future treatments for intellectual disabilities and autism.
