Abstract

Objectives:

The aim of this study was to evaluate the variant frequency of pulmonary arterial hypertension-related genes and provide theoretical basis for genetic screening of patients with pulmonary arterial hypertension further.

Methods:

Ten genes associated with pulmonary arterial hypertension were sequenced in 7 cases of idiopathic pulmonary arterial hypertension and 34 cases of congenital heart disease (CHD) associated with pulmonary arterial hypertension by next-generation high-throughput sequencing. Function prediction and gene variant amino acid conservation were carried out by bioinformatics software. Family study was performed on the patients with the variant.

Results:

A new bone morphogenetic protein receptor type 2(BMPR2) variant (c.344T>C, p. F115S) was discovered in a girl who was diagnosed with idiopathic pulmonary arterial hypertension. Her second aunt and third aunt carried the same variant and were confirmed as patients with pulmonary arterial hypertension as well. No variants or single nucleotide polymorphisms were found in other pulmonary arterial hypertension-associated genes.

Conclusions:

BMPR2 variant is the most common variant of pulmonary arterial hypertension. Genetic screening of BMPR2 variant and family survey in patients with pulmonary arterial hypertension is suggested for the sake of definite cause and better treatment.
