We also normalized EAAT2 levels to GFAP levels in ET cases and controls, and we found that ET cases still had less than half the EAAT2 levels compared with controls (0.44 ± 0.52 in ET cases vs. 0.94 ± 0.80 in controls, p =0.02). The gene discussed is SLC1A2; the disease is essential thrombocythemia.
