All evaluations, tests, procedures and treatments given study participants are used in the standard care of skeletal diseases. No experimental evaluations or treatments are offered. Patient evaluations include a medical history, review of medical records and routine physical examination. Based on the findings, other procedures may be recommended, including blood tests, urine tests, and imaging tests, such as X-rays, bone densitometry, bone scan, computed tomography (CT) and magnetic resonance imaging (MRI).
Bone specimens from participants will be collected for research use. Specimens will be obtained from bone removed during a patient s planned surgical procedure performed for medical care, or patients may be requested to have a bone biopsy removal of a small piece of bone tissue as part of the patient evaluation procedure.

Study Description:
To evaluate participants with bone and mineral disorders at the NIH Clinical Center and obtain tissue and clinical specimens from outside institutions
Objectives:
Primary Objective:
Provide a protocol within which participants with common and rare disorders of bone and mineral metabolism can be studied, evaluated and treated at NIH.
Secondary Objectives:
To obtain tissue and clinical specimens (including but not limited to blood, urine, nucleic acids, skin and bone) and data collected at outside institutions and the NIH Clinical Center from participants with various bone and mineral disorders.
Tertiary/Exploratory Objective:
Generate a pool of participants with bone and mineral disorders, from which research questions could arise and future clinical research studies may be generated.
Endpoints:
Primary Endpoint:
Medical evaluation with clinical assessments performed at time points specific to each participant s diagnosis. Analysis of research and participant outcome data will be performed.
Secondary Endpoint:
Genetic and/or biochemical assessments of surgical waste material from the NIH Clinical Center or other medical facilities.
Tertiary/Exploratory Endpoint:
Development of a database containing information from enrolled participants with bone and mineral disorders and annotated specimens and data.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This study has four objectives: 1) to provide investigators the opportunity to study bone specimens from patients with various skeletal diseases; 2) to treat patients with skeletal diseases at the NIH; 3) to expose NIH trainees to certain skeletal diseases; and 4) to gain more knowledge about skeletal diseases and stimulate further study of bone biology.
Anyone with a disease that affects the skeleton may be eligible for this study.
All evaluations, tests, procedures and treatments given study participants are used in the standard care of skeletal diseases. No experimental evaluations or treatments are offered. Patient evaluations include a medical history, review of medical records and routine physical examination. Based on the findings, other procedures may be recommended, including blood tests, urine tests, and imaging tests, such as X-rays, bone densitometry, bone scan, computed tomography (CT) and magnetic resonance imaging (MRI).

Questions about this trial
What is this clinical trial studying?
An observational study of Tumor Induced Osteomalcia and Osteomalacia, run by National Institute of Dental and Craniofacial Research (NIDCR) at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 26 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Elizabeth A Ferguson ((240) 687-3029, elizabeth.ferguson@nih.gov), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Collection of clinical and research specimens (time frame: 10 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00024804, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Oct 2026.
