A novel BMPR2 mutation associated with pulmonary arterial hypertension in an octogenarian

Area of Science:

• Cardiology
• Genetics
• Pulmonology

Background:

• Pulmonary arterial hypertension (PAH) is a severe condition characterized by high blood pressure in the lung arteries.
• Genetic mutations, particularly in the bone morphogenetic protein receptor 2 (BMPR2) gene, are known contributors to PAH development.
• Early identification of genetic factors is crucial for understanding disease mechanisms and potential therapeutic targets.

Observation:

• An 83-year-old male patient presented with severe PAH.
• The patient had a documented family history of pulmonary hypertension.
• Genetic testing revealed a novel mutation in the BMPR2 gene.

Findings:

• The patient represents the oldest reported individual diagnosed with PAH and identified with a BMPR2 gene mutation.
• The discovery of this novel mutation in an elderly patient suggests a broader spectrum of genetic influences on PAH.
• This finding challenges previous assumptions about the typical age of onset for BMPR2-associated PAH.

Implications:

• This case expands the understanding of the genetic basis of PAH, particularly concerning BMPR2 mutations.
• It highlights the importance of genetic screening in elderly patients presenting with unexplained pulmonary hypertension.
• Further research into this novel mutation may reveal new insights into PAH pathogenesis and inform personalized treatment strategies.
