In patients harboring biallelic variants in CNTNAP2, brain MRI may be normal, such as in our case, or show cortical dysplasia (cortical dysplasia-focal epilepsy syndrome, CDFES).1–3 Additional findings include cerebellar abnormalities (vermian hypoplasia or atrophy) and nonspecific white matter abnormalities.1,2. The gene discussed is CNTNAP2; the disease is cerebral cortical dysplasia.
