| Interpretive Data: |
Background Information for: Pulmonary Arterial Hypertension (BMPR2) Sequencing:
Characteristics: Primary pulmonary arterial hypertension (PAH) is caused by widespread occlusion/destruction of the smallest pulmonary arteries that increases resistance to blood flow.
Incidence: 1 to 2 new cases per million individuals per year.
Inheritance: Autosomal dominant.
Penetrance: Approximately 20 percent.
Cause: Pathogenic BMPR2 mutations.
Clinical Sensitivity: Approximately 37 percent for familial PAH and 15 percent for idiopathic PAH.
Methodology: Bidirectional sequencing of the entire BMPR2 coding region and intron-exon boundaries.
Analytical Sensitivity & Specificity: 99 percent.
Limitations: Rare diagnostic errors can occur due to primer site mutations. Regulatory region and deep intronic mutations and large deletion/duplications will not be detected. Mutations in genes, other than BMPR2, are not evaluated.
Counseling and informed consent are recommended for genetic testing. Consent forms are available online at www.aruplab.com.
