Published in 2019 at "Annals of Clinical and Translational Neurology"

DOI: 10.1002/acn3.768

Abstract: Developmental and epileptic encephalopathies are characterized by infantile seizures and psychomotor delay. Glycosylphosphatidylinositol biosynthesis defects, resulting in impaired tethering of various proteins to the cell surface, represent the underlying pathology in some patients. One of… read more here.

Published in 2023 at "Epilepsia Open"

DOI: 10.1002/epi4.12739

Abstract: Gamma‐aminobutyric acid (GABA), the major inhibitory neurotransmitter in the adult central nervous system, plays an important role during embryonic neural network formation. GAD67 is the rate‐limiting enzyme in GABA synthesis, and its deficiency leads to… read more here.
