For example, it was previously reported that the mean NR2A/2B antibody level (ng/mL) in patients with ischemic stroke was 5.01 ± 1.23 (range, 3.24–7.21), in patients with TIA it was 4.02 ± 2.04 (range, 2.71–7.23), and in patients with hypertension/atherosclerosis it was 1.72 ± 0.23, while in controls it was only 1.49 ± 0.22 (range, 1.02–1.98) [26]. This evidence concerns the gene GRIN2A and ischemic stroke.
