Is Recurrent Respiratory Papillomatosis hereditary?

Recurrent Respiratory Papillomatosis (RRP) is not considered a hereditary or genetic condition, as it is caused by an infection with the human papillomavirus (HPV), typically types 6 and 11. Because the disease is viral rather than inherited, it does not follow Mendelian inheritance patterns and cannot be passed down through family genes.

Is Recurrent Respiratory Papillomatosis hereditary?

Recurrent Respiratory Papillomatosis is definitively not a hereditary condition. It is a viral disease characterized by the growth of benign tumors (papillomas) in the respiratory tract. While some researchers investigate whether certain immune system variations might make some individuals more susceptible to persistent HPV infection, Recurrent Respiratory Papillomatosis is not caused by a mutation in the germline DNA that is passed from parent to child.

How does Recurrent Respiratory Papillomatosis transmission occur?

The transmission of Recurrent Respiratory Papillomatosis is primarily associated with vertical transmission from an infected mother to her child during the birthing process. However, the risk of a child developing the condition from an infected parent is extremely low, estimated to be less than 1% among infants exposed to HPV during delivery. The condition is categorized into two forms:

• Juvenile-onset Recurrent Respiratory Papillomatosis: Typically diagnosed in children under age 5, often linked to vertical transmission.


• Adult-onset Recurrent Respiratory Papillomatosis: Usually diagnosed between ages 20 and 40, often linked to sexual transmission of HPV.

Is genetic testing recommended for Recurrent Respiratory Papillomatosis?

Because Recurrent Respiratory Papillomatosis is not a genetic disorder, there are no diagnostic genetic tests available or recommended to identify a predisposition to the disease. Genetic counseling is generally not required for families affected by the condition, as there is no risk of passing a "disease gene" to offspring. If you are concerned about HPV, the most effective preventative measure is the HPV vaccination, which protects against the specific virus strains that cause Recurrent Respiratory Papillomatosis.

Next steps

• Consult an otolaryngologist (ENT specialist) for the management of airway papillomas.


• Discuss the HPV vaccine with your primary care physician to reduce the risk of infection.


• Connect with the 156 community members on DiseaseMaps.org who share experiences with Recurrent Respiratory Papillomatosis.


• Monitor for symptoms such as chronic hoarseness or difficulty breathing, which warrant immediate clinical evaluation.
