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: Diagnostic errors can occur due to rare sequence variations. Regulatory region and deep intronic mutations and large deletion/duplications will not be detected. Mutations in genes, other than BMPR2, are not evaluated.

Compliance Statement C: For human genetic inheritable conditions and mutations. This test was developed and its performance characteristics determined by ARUP Laboratories. The U. S. Food and Drug Administration has not approved or cleared this test; however, FDA clearance or approval is not currently required for clinical use. The results are not intended to be used as the sole means for clinical diagnosis or patient management decisions.

Counseling and informed consent are recommended for genetic testing. Consent forms are available online.
