A rare compound heterozygous EIF2AK4 mutation in pulmonary veno-occlusive disease
Abstract Background Pulmonary veno-occlusive disease (PVOD) is a rare, progressive, and oft-fatal condition of pulmonary arterial hypertension that is typically difficult to diagnose and treat. However, with the development of next-generation sequencing technology, an increasing number of patients w...

description | Abstract Background Pulmonary veno-occlusive disease (PVOD) is a rare, progressive, and oft-fatal condition of pulmonary arterial hypertension that is typically difficult to diagnose and treat. However, with the development of next-generation sequencing technology, an increasing number of patients with PVOD are being diagnosed. Methods Initially, we used whole exome sequencing (WES) to identify the proband as a rare compound heterozygous mutation of EIF2AK4 in PVOD. Subsequently, the parents of patient underwent EIF2AK4 screening by Sanger sequencing. Results In this study, we describe the family tree of a patient with PVOD with a rare compound heterozygous EIF2AK4 mutation. Moreover, we identified a new EIF2AK4 mutation, c.2236_2237insAAGTCCTTCT, in exon 12 of the proband and his mother. This frameshift mutation led to premature termination of the coding protein sequence and widespread loss of protein function, which promoted the development of PVOD. Conclusions Our results expand our understanding of the EIF2AK4 mutation spectrum in patients with PVOD, as well as highlight the clinical applicability of WES. |
