a Brain MRI. Cranial magnetic resonance T2-weighted images showed widening of the septum pellucidum with formation of the fifth and sixth ventricles, a slightly wider median cleft of the brain, and bifrontal gyral atrophy. b Sanger sequencing verified the de novo GRIN2B c.870(exon3)del, as the parents were wild type at this site. c, d Scalp EEG. Interictal single or continuous spike slow waves were recorded at F7 and T5 both on average lead (c) and bipolar (d)
