Is this trial a fit for you?

Likely a good fit

Ideal candidates include families with confirmed cases of IBMFSs showing signs of bone fragility fractures.

Probably not a fit

Patients diagnosed with paroxysmal nocturnal hemoglobinuria or de novo myelodysplastic syndrome may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study investigates the genetic factors associated with unclassifiable inherited bone marrow failure syndromes (IBMFSs) that lead to bone fragility fractures. By conducting whole-exome sequencing on affected families, the research aims to clarify the underlying pathophysiological mechanisms and improve diagnosis, management, and prognosis for patients. The study also seeks to identify novel clinical entities within the spectrum of IBMFSs to enhance treatment strategies and prevent complications.

Why it matters

Potential benefit: If successful, this study could lead to improved diagnostic accuracy and management strategies for patients with inherited bone marrow failure syndromes.

How similar studies have gone: While similar studies have explored genetic causes of bone marrow failure, this specific focus on unclassifiable IBMFSs is relatively novel.

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Confirmed a two-generational family with IBMFSs presented with signs and symptoms of bone fragility fractures and admitted or treated in Hematology Division at Internal Medicine Departments of various university hospitals will be screened for enrollment in this study.
* The investigators will invite the entire family for testing for IBMFSs mutations, and three additional family members consented to participate in this study.

Exclusion Criteria:

* • Patients will be diagnosed with paroxysmal nocturnal hemoglobinuria

  * Patients will be diagnosed with de novo myelodysplastic syndrome
  * IBMFSs-patients will refuse to consent to this study.
  * Serologic evidence of recent virus infection as hepatitis A (HAV), HBV, HCV, HEV, cytomegalovirus (CMV), Epstein-Barr virus (EBV), or positive test for HIV.
  * IBMFSs patients with severe systemic diseases (such as cardiovascular, renal, and hepatic disease) or surgical/medical conditions that might interfere with follow-up instructions.
  * IBMFs patients with psychiatric disorders or a history of drug abuse,
