In agreement with our findings, samples from patients with Focal Cortical Dysplasia, which display many cellular similarities with TSC lesions, contain a small subset of dysmorphic neurons that express VGAT and DLX1 or DLX2 transcription factors expressed by cells derived from the medial ganglionic eminences (Lamparello et al., 2007). The gene discussed is DLX2; the disease is tuberous sclerosis.
