We report an unusual seizure phenotype in a girl with a de novo NAA10 pathogenic variant.

Ogden syndrome is an extremely rare X-linked neurodevelopmental disorder characterized by postnatal growth failure, severely delayed psychomotor development, variable dysmorphic features, neonatal hypotonia progressing to hypertonia and diffuse cerebral atrophy.
