TL;DR: The results demonstrate that the significantly increased burden of large and rare micro deletions in GGE patients is largely confined to recurrent hotspot microdeletions and microde letions affecting neurodevelopmental genes, suggesting a strong impact of fundamental neuro developmental processes in the pathogenesis of common GGE syndromes.
