HHTNext®
Use
Hereditary hemorrhagic telangiectasia (HHT) is characterized by arteriovenous malformations, spontaneous and recurrent nosebleeds (epistaxis), and telangiectases. Genetic testing for HHT can establish or confirm a diagnosis, identify the affected gene for accurate family testing, and determine the presence or absence of a mutation identified in a family member. This information aids in determining future risks and guiding medical management recommendations for individuals diagnosed with HHT.

Limitations
The HHTNext test is designed to detect >99% of described mutations in the genes tested. However, exon-level resolution may not be achieved for every gene, and technical limitations may prevent detection of all pathogenic variants. Results may also vary based on clinical and family history, and certain DNA or protein changes that cause disease might not be detected due to technological or knowledge limitations.
