Pulmonary arterial hypertension (PAH) is a progressive and fatal disease for
which there is an ever-expanding body of genetic and related pathophysiological
information on disease pathogenesis. Many germline gene mutations have now been
described, including mutations in the gene coding bone morphogenic protein
receptor type 2 (BMPR2) and related genes. Recent advanced gene-sequencing
methods have facilitated the discovery of additional genes with mutations among
those with and those without familial forms of PAH (CAV1, KCNK3, EIF2AK4). The
reduced penetrance, variable expressivity, and female predominance of PAH suggest
that genetic, genomic, and other factors modify disease expression. These
multi-faceted variations are an active area of investigation in the field,
including but not limited to common genetic variants and epigenetic processes,
and may provide novel opportunities for pharmacological intervention in the near
future. They also highlight the need for a systems-oriented multi-level approach
to incorporate the multitude of biological variations now associated with PAH.
Ultimately, an in-depth understanding of the genetic factors relevant to PAH
provides the opportunity for improved patient and family counseling about this
devastating disease.
