Epileptic Encephalopathy in Adams-Oliver Syndrome Associated to a New DOCK6 Mutation: A Peculiar Behavioral Phenotype.

Adams-Oliver syndrome (AOS) is characterized by a combination of congenital scalp defects (aplasia cutis congenita) and terminal transverse limb malformations of variable severity. When neurological findings are present, patients are reported as AOS variants. We describe a child with compound heterozygosity of the DOCK6 gene, aplasia cutis, terminal transverse limb defects, cardiovascular impairment, intellectual disability, and brain malformations with intracranial calcifications. He suffers from a severe refractory epileptic encephalopathy characterized by polymorphic seizures with prolonged periods of electroencephalogram (EEG), continuous epileptiform activity related to clinical inactivity, and closure of eyes with an "ON-OFF" behavior.
