| Outline of Final Research Achievements |
Pulmonary arterial hypertension (PAH) is a progressive, fatal disease even in the pediatric patients.Genetic mutations in the BMPR2 gene, ALK1 gene, and SMAD8 gene etc. have been detected in PAH so far. But, about 60% of PAH patients have no mutations. This fact indicates that there remain unidentified genes associated with PAH.
We detected novel mutations in HIVEP gene, which is in the BMP/TGFb signal cascade in two idiopathic PAH patients.However,in protein functional analysis, we have not yet shown the evidence of disease causality of thease mutations.
