Abstrakt: The aim of this study is to report three cases of epilepsy with eyelid myoclonia (EEM) with CHD2 pathogenic variants. A database of 134 patients with EEM evaluated at Mayo Clinic sites was searched to identify patients with CHD2 variants. The medical records of those identified were reviewed to describe their presentation, treatment, and clinical course. Three patients (2 males, 1 female) with EEM were found to harbor de novo CHD2 pathogenic variants (c.2636C>T p.(Ala879Val), c.3734delA p. (Lys1245Asnfs*4), and c.3896delTinsCG p. (Val1299Alafs*5)). All three patients had comorbid autism spectrum disorder (ASD), intellectual disability (ID), and attention deficit disorder (ADHD). Eyelid myoclonia was a prominent seizure type that persisted in the three patients despite trials of multiple antiseizure medications. Generalized tonic-clonic seizures occurred in two of the patients but were controlled with antiseizure medications. Genetic testing should be considered in patients presenting with EEM, especially when ADHD, ID, ASD, and drug-resistant seizures are present. Further understanding of the relationship between CHD2 variants and epileptogenesis may provide important insights into the pathogenesis of EEM.
