Background Information for BMP9/GDF2 Sequencing: Characteristics: Telangiectases (blanching pink to red vascular lesions) of the hands, mouth, face, limbs and trunk. Epistaxis (recurring nosebleeds). Prevalence: Unknown. Inheritance: Autosomal dominant. Penetrance: NA. Cause: Pathogenic BMP9/GDF2 gene mutations. Clinical Sensitivity:BMP9/GDF2 mutations detected in ~1 percent of individuals suspected to have a hereditary telangiectasia syndrome, but with no mutation in the ACVRL1, ENG or SMAD4 genes. Methodology: Bidirectional sequencing of the entire BMP9 coding region and intron-exon boundaries. Analytical Sensitivity and Specificity: 99 percent. Limitations: Diagnostic errors can occur due to rare sequence variations. Regulatory region mutations, deep intronic mutations, and large deletions/duplications will not be detected.
