Abstract excerpt
BACKGROUND: Optical genome mapping (OGM) is a novel technology that enables high-resolution detection of structural variants. This study aimed to evaluate the diagnostic contribution of OGM in early-onset developmental epileptic encephalopathies (DEEs) with unresolved genetic causes. MATERIALS AND METHODS: A total of 38 children with early-onset DEEs (aged 0-18 years) who remained undiagnosed despite conventional...
