Elevated plasma levels of the autoantibodies to NR2A/2B NMDA receptor subunits in plasma were reported in patients with TIAs and ischemic stroke, and the levels of NR2A/2B autoantibodies measured within 72 h differentiated ischemic stroke from intracerebral hemorrhage (ICH) [16]. The gene discussed is GRIN2A; the disease is intracerebral hemorrhage.
