"Response by Hadinnapola et al to Letter Regarding Article, ""Phenotypic Characterization of EIF2AK4 Mutation Carriers in a Large Cohort of Patients Diagnosed Clinically With Pulmonary Arterial Hypertension""."
In this study we assessed if EIF2AK4 mutations occur also in a family with autosomal dominantly inherited pulmonary arterial hypertension (HPAH) and incomplete penetrance of bone morphogenic protein receptor 2 (BMPR2) mutations.
We applied SNP-array-based homozygosity mapping in three families and obtained, among others, one of which included the gene EIF2AK4, recently reported in patients with PAH from group-1' pulmonary veno-occlusive disease (PVOD) and pulmonary capillary hemangiomatosis (PCH).
