Is Ledderhoses Disease / Plantar Fibromatosis hereditary?

TL;DR: Ledderhose disease, also known as plantar fibromatosis, is considered a complex condition with a likely genetic predisposition, though it does not follow simple Mendelian inheritance patterns. While it is not strictly classified as a single-gene hereditary disorder, it often shows familial clustering, suggesting that both genetic susceptibility and environmental factors play a role in its development.

Is Ledderhose disease considered a hereditary condition?

In the field of medical genetics, it is important to distinguish between "genetic" (caused by changes in DNA) and "hereditary" (passed directly from parent to child). Ledderhose disease is best described as a condition with a strong genetic predisposition. While it is not caused by a single, predictable mutation like cystic fibrosis, it frequently occurs in families, which suggests an underlying genetic susceptibility. We often observe this condition alongside other fibromatoses, such as Dupuytren’s contracture (of the hand) or Peyronie’s disease, reinforcing the idea that a shared genetic trait may increase a person’s likelihood of developing these fibrous growths.

What is the inheritance pattern of Ledderhose disease?

Ledderhose disease does not follow a classic Mendelian inheritance pattern, such as autosomal dominant or autosomal recessive transmission. Instead, it is likely multifactorial. This means that an individual’s risk of developing Ledderhose disease is influenced by a combination of multiple genetic variations and external factors, such as mechanical stress on the feet, alcohol consumption, or diabetes. Because the inheritance is complex, we cannot provide a specific percentage risk for children of an affected parent; however, the presence of the condition in multiple generations of a family is a well-documented clinical observation.

Is genetic testing available for Ledderhose disease?

Currently, there is no routine, clinically available genetic test to confirm a diagnosis of Ledderhose disease. Because the exact genetic markers associated with the condition are still being researched, diagnosis remains a clinical process based on physical examination, patient history, and imaging (such as ultrasound or MRI). Genetic testing is not standard practice for Ledderhose disease, as a positive test would not currently change the clinical management or treatment plan for the patient.

What role does genetic counseling play for families?

For those concerned about the familial nature of Ledderhose disease, genetic counseling can provide significant peace of mind. A genetic counselor can help families by:

• Reviewing the family medical history to identify patterns of fibromatosis.


• Providing education on the multifactorial nature of the condition to reduce anxiety regarding "passing it on."


• Coordinating with orthopedic specialists to ensure that family members at risk are monitored for early symptoms.


• Discussing the lack of prenatal diagnostic options, as Ledderhose disease is generally managed as an adult-onset condition.

Are de novo mutations common in this condition?

The term "de novo" refers to a new mutation that occurs in an individual for the first time. Given that Ledderhose disease is likely multifactorial rather than a single-gene disorder, it is more accurate to view it as the result of a predisposition rather than a single, spontaneous genetic "error." Many individuals develop Ledderhose disease without a clear family history, which highlights that environmental triggers and lifestyle factors are just as significant as the underlying genetic blueprint.

Next steps

• Consult a podiatrist or orthopedic surgeon to discuss non-surgical management options for Ledderhose disease.


• Document your family medical history, specifically noting relatives with hand contractures (Dupuytren’s) or other fibrous conditions.


• Join the DiseaseMaps.org community to connect with 95 other members who are navigating life with this condition.


• Maintain a proactive foot care routine and monitor for changes in the size or texture of nodules.
