The study investigates a neurodevelopmental disorder (-RD) caused by mutations in the MUNC18-1 gene, leading to symptoms like developmental delay and seizures, with varying severity among patients.
Using advanced techniques, researchers analyzed neurons derived from patients' stem cells, finding reduced levels of the MUNC18-1 protein, along with dysregulated proteins linked to synapse function and altered neuronal network activity.
The findings reveal common cellular traits across patients with -RD while also highlighting distinct phenotypic differences, suggesting varied underlying mechanisms of the disorder that could inform future research and therapy development.
