Table 3 Clinical phenotypes of FBLN2 and PDGFD variant carriers. Sex ratios and mean ± SD diagnostic age and hemodynamic values have been calculated separately for FBLN2 and PDGFD variant carriers

From: Rare variant analysis of 4241 pulmonary arterial hypertension cases from an international consortium implicates FBLN2, PDGFD, and rare de novo variants in PAH
