SYNGAP1 mutations: Clinical, genetic, and pathophysiological features.
Agarwal M, Johnston MV, Stafstrom CE. Agarwal M, et al. Int J Dev Neurosci. 2019 Nov;78:65-76. doi: 10.1016/j.ijdevneu.2019.08.003. Epub 2019 Aug 24. Int J Dev Neurosci. 2019. PMID: 31454529 Review.
Here we review the clinical and pathophysiological aspects of SYNGAP1 mutations with a focus on their effect on synaptogenesis, neural circuit function, and cellular plasticity. We conclude by comparing the molecular pathogenesis of SYNGAP1 mutations w …
