To assess the potential role of the Zn2+–MTF1–CaV3.2 cascade in human TLE, we analysed hippocampal MTF1 and CaV3.2 expression levels in pharmacoresistant TLE patients with hippocampal sclerosis (HS) versus patients with ‘lesion-associated' TLE (Supplementary Note 1). The gene discussed is CACNA1H; the disease is histiocytic sarcoma.
