TREM2 and Hypertension: ACD exhibits genetic pleiotropy with vascular risk factors (hypertension, WMH burden), hematological traits (neutrophil, lymphocyte count), and blood‐based biomarkers indicative of inflammation (C‐reactive protein levels), hemostasis (fibrinogen, factor‐VII levels), and neurodegeneration (soluble TREM2 levels) (Table S6).
