Sporadic periventricular nodular heterotopia: Classification, phenotype and correlation with Filamin A mutations

The purpose of this study was to better delineate the clinical spectrum of periventricular nodular heterotopia (PNH) in a large patient population after long term follow up. Specifically, this study aimed to relate PNH subtypes to clinical or epileptic outcomes, epileptic discharges and underlying Filamin A (FLNA) mutations by analyzing anatomical features.The study included 100 patients with radiologically confirmed nodular heterotopia....
