Although the discussion was mainly focused on the gene SP1 that presented significant expression change in the case of stroke, other genes with minor expression variances may also worth a closer look, including PF4 (LFC: 0.79; p-value< 10–3), CYP4V2(LFC: 0.72; p-value = 0.046). The gene discussed is CYP4V2; the disease is stroke disorder.
