Reductions in the expression of adhesion molecules in neurons, such as PPM1H, NTSR2, CLDN10, and CDH13, are related to synaptic N‐methyl‐D‐aspartate (NMDA) receptor‐induced long‐term potentiation69 and affect serotonin (5‐HT) formation, which is potentially relevant to migraine.70, 71. The gene discussed is CLDN10; the disease is migraine disorder.
