He also presented with periventricular white matter cysts, a feature not systematically reported in previous series, but lacked the hallmark craniofacial features, cortical malformations, and seizure history typical of BWCFFS. Notably, he had no history of unprovoked or febrile seizures, and there were no clinical episodes suggestive of epilepsy, which may indicate a milder neurological phenotype within the 7p21.1 microdeletion encompassing the ACTB spectrum. Here, ACTB is linked to epilepsy.
