What this trial studies

This observational study aims to investigate the natural history and pathogenesis of melorheostosis, a rare osteosclerotic disease characterized by excessive bone growth. Participants aged 18 and over with melorheostosis, as well as their unaffected relatives, will undergo comprehensive evaluations including medical history, physical exams, and various tests such as blood and urine collection, X-rays, and neurological assessments. The study will follow participants over time to assess disease progression and explore potential genetic factors associated with the condition.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and over with suspected or confirmed melorheostosis.

Not a fit: Patients who are pregnant, lactating, or under 18 years old will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the causes and progression of melorheostosis, potentially leading to improved management strategies for patients.

How similar studies have performed: While studies on melorheostosis are limited, the approach of investigating the natural history of rare diseases has shown promise in other contexts.

Eligibility criteria

Show full inclusion / exclusion criteria
* INCLUSION CRITERIA:

All eligible patients are invited to participate in this protocol. Patients are adults aged \> 18 years with possible melorheostosis (suspected or confirmed). Since both men and women are affected with the disease, both sexes will be studied. All ethnic and racial groups are at risk and will be included.

Relatives of patients with melorheostosis may be included for genetic testing only.

EXCLUSION CRITERIA:

* Pregnant or lactating women. A pregnancy test is performed in women of childbearing potential (up to age 55) unless they have a history of hysterectomy or tubal ligation.
* Children (age less than 18 years) are excluded.
* Subjects with severe active infection or other co-morbidities that in the opinion of the investigator would warrant exclusion.
* Subjects unable to provide informed consent.
