DPPA4 and pulmonary artery enlargement: Interestingly, the DPPA4 DMP (cg14836960) correlated significantly with FOXP2 (cg18546840: r = 0.491, P = 0.009, cg24786986: r = 0.466, P = 0.0014, respectively, n = 27, Pearson correlation) and TACR3 (cg16461251: r = 0.415, P = 0.031, n = 27, Pearson correlation) DMPs in the early PAE subgroup, but no correlations were observed in the all PAE placentas group.
