Is Von Hippel-Lindau Disease contagious?

Von Hippel-Lindau (VHL) disease is not contagious, infectious, or transmissible in any way through contact, bodily fluids, or proximity to others. It is a rare genetic condition caused by a mutation in the VHL gene, which means it cannot be "caught" from someone else or spread through social interaction.

What is the actual cause of Von Hippel-Lindau disease?

Von Hippel-Lindau disease is an autosomal dominant genetic disorder. This means it is caused by a germline mutation in the VHL tumor suppressor gene located on chromosome 3. Because this mutation is present in a person's DNA, it is inherited from a parent or occurs as a new (de novo) mutation during early development. The VHL gene normally produces a protein that prevents the growth of tumors; when this gene is mutated, the body loses this regulatory control, leading to the growth of various benign and malignant tumors, such as hemangioblastomas, renal cell carcinomas, and pheochromocytomas.

Why is there sometimes confusion regarding the contagiousness of Von Hippel-Lindau disease?

The confusion surrounding the contagiousness of Von Hippel-Lindau disease often stems from a lack of public awareness regarding rare genetic disorders. Because the condition involves the growth of tumors, some people mistakenly associate it with infectious diseases like viruses or bacteria that can spread. Furthermore, because Von Hippel-Lindau disease requires lifelong medical surveillance and sometimes surgery, the intensity of the clinical care can be misinterpreted by those unfamiliar with the condition as a sign of a "sickness" that might be catching. It is important to emphasize that there is absolutely zero risk in living with, touching, or being near someone who has been diagnosed with Von Hippel-Lindau disease.

Are there environmental triggers for Von Hippel-Lindau disease?

There are no environmental triggers that can cause a person to develop Von Hippel-Lindau disease. Since the condition is rooted in a genetic mutation present from conception, it is not caused by diet, lifestyle, exposure to pathogens, or environmental toxins. While environmental factors might influence the general health of a patient, they do not cause the underlying genetic disorder. Understanding this is vital for reducing the stigma that patients sometimes face, as it clarifies that the disease is a biological reality for the individual, not a consequence of external behavior or contagion.

Key facts to remember about VHL

• Genetics: Von Hippel-Lindau disease is caused by a mutation in the VHL gene.


• Transmission: It is impossible to transmit the condition to another person through casual contact, kissing, sharing food, or intimacy.


• Prevalence: The estimated prevalence of Von Hippel-Lindau disease is approximately 1 in 36,000 individuals worldwide.


• Community Support: At DiseaseMaps.org, over 100 people with Von Hippel-Lindau disease have connected to share experiences, highlighting the importance of community in managing this rare condition.

Next steps

• Consult with a clinical geneticist to discuss genetic testing if you or a family member show symptoms or have a family history of Von Hippel-Lindau disease.


• Schedule regular screenings with an oncologist or a specialist familiar with the management of VHL-associated tumors.


• Join the DiseaseMaps.org community to connect with other patients and families navigating the realities of Von Hippel-Lindau disease.


• Educate friends and family members by sharing reliable resources from the VHL Alliance to dispel myths about the condition.
