Is Dent Disease contagious?

Dent disease is not contagious and cannot be spread through contact, air, or bodily fluids. It is a rare, inherited X-linked genetic disorder that affects the kidneys, meaning there is zero risk to family members, friends, or caregivers when spending time with someone who has the condition.

What is the actual cause of Dent disease?

Dent disease is a rare genetic disorder characterized by proximal renal tubular dysfunction. It is caused by mutations in specific genes, most commonly the CLCN5 gene (Dent disease type 1) or the OCRL gene (Dent disease type 2). Because it is a genetic condition, it is present from birth, although symptoms may not become clinically apparent until childhood or early adulthood. There is no infectious agent, such as a virus or bacteria, involved in the development of Dent disease.

Why is Dent disease sometimes misunderstood?

Because Dent disease involves complex symptoms like excessive protein in the urine (proteinuria), kidney stones (nephrolithiasis), and nephrocalcinosis, individuals may mistakenly assume these health issues are caused by an infection. Furthermore, the rarity of Dent disease means that many people—including some medical professionals—may be unfamiliar with the diagnosis, leading to unnecessary confusion or stigma. It is vital to emphasize that being near, touching, or living with someone who has Dent disease poses absolutely no health risk to others.

Is Dent disease hereditary?

Yes, Dent disease follows an X-linked recessive inheritance pattern. This means:

• It primarily affects males, as they have only one X chromosome.


• Females who carry the mutation are typically asymptomatic but can pass the gene to their children.


• Approximately 60-70% of cases are caused by mutations in the CLCN5 gene.


• A clinical geneticist can provide testing to confirm the specific mutation involved in a family.

Next steps

• Consult a nephrologist who specializes in genetic kidney disorders for ongoing management.


• Connect with the 10 members currently sharing their experiences with Dent disease on DiseaseMaps.org to find community support.


• Speak with a genetic counselor to understand the implications of the diagnosis for your family.


• Educate family members and teachers to dispel myths and reduce social stigma surrounding the condition.
