After BH FDR multiple testing correction, only 2 traits were significantly associated with risk of PAH: the proportion of Vδ1+ T cells (IVW, P=0.00006, β=−1.02) and the proportion of CD1c‐ myeloid dendritic cells (IVW, P=0.00076, β=0.84). The gene discussed is CD1C; the disease is pulmonary arterial hypertension.
