Is Relapsing Polychondritis hereditary?

Relapsing polychondritis is not considered a hereditary or strictly genetic disease, as there is currently no evidence that it is passed down through families in a predictable pattern. While the exact cause remains unknown, it is classified as an immune-mediated condition rather than a genetic disorder, meaning it is not caused by a single inherited mutation.

Is Relapsing Polychondritis a genetic condition?

Current medical research indicates that relapsing polychondritis is an autoimmune disease where the body’s immune system mistakenly attacks its own cartilaginous tissues. Unlike genetic disorders caused by a specific mutation in a person's DNA, relapsing polychondritis does not follow Mendelian inheritance patterns such as autosomal dominant or recessive transmission. Because it is not an inherited condition, there is no known risk percentage for children of an affected parent, and it is not considered a familial disease.

Why does Relapsing Polychondritis occur?

While the precise trigger for relapsing polychondritis is not fully understood, researchers believe it may involve a complex interplay between environmental factors and an individual's unique immune system regulation. Because relapsing polychondritis is not caused by a single, spontaneous (de novo) mutation, genetic testing is not currently used as a diagnostic tool. Diagnosis is instead based on clinical criteria, including:

• Inflammation of ear cartilage


• Seronegative inflammatory arthritis


• Inflammation of nasal cartilage


• Ocular inflammation (e.g., scleritis or uveitis)


• Airway cartilage inflammation

Is genetic counseling recommended?

Since relapsing polychondritis is not an inherited condition, formal genetic counseling is not typically required for family planning. However, for those living with relapsing polychondritis, consultation with a rheumatologist is essential to manage the systemic inflammation that characterizes the disease. Because the condition involves the immune system, patients often find support by connecting with others through the DiseaseMaps.org community, where 468 individuals share their experiences managing this rare condition.

Next steps

• Consult a board-certified rheumatologist to discuss personalized symptom management.


• Monitor for respiratory or ocular symptoms, which require urgent medical evaluation.


• Join the relapsing polychondritis community at DiseaseMaps.org to connect with others and share experiences.


• Keep a detailed log of flare-ups to assist your physician in adjusting corticosteroid or immunosuppressive therapies.
