Seizure semiology and electroencephalographic (EEG) manifestations of autoimmune-mediated cerebral
folate deficiency
(CFD) before and after therapy have yet to be fully characterized. Here, we report these findings in two such patients. Our first patient presented with the novel manifestation of infantile spasms at the age of 3months, while the second developed the previously reported initial onset of tonic seizures with static developmental delay, but subsequently manifested the novel finding of electrical
status epilepticus
in sleep at the age of 15years. Awareness of these new manifestations, together with the previously reported manifestations of developmental delay, seizure onset during the first 2years of life, occurrence of tonic, myoclonic-astatic, absence, and generalized tonic-clonic seizures, with an EEG of generalized spike-slow waves and multifocal spikes, is important to increase the index of suspicion of this treatable disorder.

KCNH1 mutations have been identified in patients with Zimmermann-Laband syndrome and Temple-Baraitser syndrome, as well as patients with uncharacterized syndromes with intellectual disability and overlapping features. These syndromes include dysmorphic facial features, nail hypo/aplasia, thumb and skeletal anomalies, intellectual disability, and seizures. We report the epilepsy phenotype in patients with KCNH1 mutations. Demographic data, electroclinical features, response to antiepileptic drugs, and results of significant diagnostic investigations of nine patients carrying mutations in KCNH1 were obtained from referring centres. Epilepsy was present in 7/9 patients. Both generalized and focal tonic-clonic seizures were observed. Complete seizure control was achieved with pharmacological treatment in 2/7 patients; polytherapy was required in 4/7 patients.
Status epilepticus
occurred in 4/7 patients. EEG showed a diffusely slow background in 7/7 patients with epilepsy, with variable epileptiform abnormalities. Cerebral
folate deficiency
and an increase in urinary hypoxanthine and uridine were observed in one patient. Epilepsy is a key phenotypic feature in most individuals with KCNH1-related syndromes, suggesting a direct role of KCNH1 in epileptogenesis, although the underlying mechanism is not understood.
