Whole exome sequencing to identify a novel gene (caveolin-1) associated with human pulmonary arterial hypertension.
Heritable and idiopathic pulmonary arterial hypertension (PAH) are phenotypically identical and associated with mutations in several genes related to transforming growth factor (TGF) beta signaling, including bone morphogenetic protein receptor type 2, activin receptor-like kinase 1, endoglin, and mothers against decapentaplegic 9. Approximately 25% of heritable cases lack identifiable mutations in any of these genes. ⋯ Our study represents successful elucidation of a dominant Mendelian disorder using whole exome sequencing. Mutations in CAV1 are associated in rare cases with PAH. This may have important implications for pulmonary vascular biology, as well as PAH-directed therapeutic development.
