Only the relative duration of epilepsy (normalized to age) correlated to lowered myelination of MBP and CNPase staining (Kendall‐tau b; MBP R = −0.325, P = 0.002*, CNPase R = −0.264, P = 0.011; data not shown) and to mTOR activation (Kendall‐tau b; pS6 R = 0.338, P = 0.001*, vim R = 0.274; P = 0.011; data not shown). The gene discussed is MTOR; the disease is epilepsy.
