Trial summary

This study will determine the biochemical and genetic causes of inherited immune diseases affecting lymphocyte homeostasis. Lymphocytes are a type of white blood cell that fights infections. Normally, the body keeps a precise balance in which lymphocyte growth is matched by lymphocyte death. Read more about this study

Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 1 month to 100 years
  • All sexes
  • No healthy volunteers
  • Child, Adult, Older adult

Study population: Patients referred by physician with a suspected inherited immune deficiency and their unaffected relatives.

Who may be able to join

  • Patients known to have or suspected of having an inherited immune cell homeostasis, programmed cell death susceptibility syndrome, lymphocyte developmental block, or defective immune cell effector functions will be eligible for enrollment. We will enroll
  • patients with suspected disease if the investigator agrees that there is a high index of suspicion. Blood relatives of enrolled patients will be eligible for enrollment. There will be no limit as to age, sex, race, or disability.

Who cannot join

  • Severely debilitated health status or poor venous access may preclude obtaining adequate specimens for analysis. The minimum weight for infants on this protocol is 3 kg because of the limits of maximal acceptable blood draw volumes and minimum requirement for core laboratory tests would exceed the acceptable volume.
  • Co-enrollment guidelines: Participants may be co-enrolled in other studies including NIH protocols 05-I-0213, 93-I-0063 and 17-I-0122. Participants should inform the investigator of participation in other research studies.

About this study

This study will determine the biochemical and genetic causes of inherited immune diseases affecting lymphocyte homeostasis. Lymphocytes are a type of white blood cell that fights infections. Normally, the body keeps a precise balance in which lymphocyte growth is matched by lymphocyte death. People with constantly enlarged lymph nodes or spleen, along with autoimmune disease, immunodeficiency, lymphoma, or other immune problems affecting lymphocytes may have an abnormality of the immune system in the cell growth and cell death processes that regulate lymphocyte homeostasis.

Patients who have, or are suspected of having, an inherited lymphocyte homeostasis or programmed cell death susceptibility syndrome may be eligible for this study. Relatives of patients are also included.

Read more

Participants' (patients and relatives) medical records are reviewed and blood samples are drawn for studies to identify genes involved in immune disorders. Tissues that have been removed from patients for medical reasons, such as biopsied tissues, may be examined for tissue and DNA studies. Relatives are studied to determine if some of them may have a very mild form of lymphocyte homeostasis disorder.

Patients who have an immune problem that the researchers wish to study further will be invited to donate additional blood samples at irregular intervals (at least once a year) and to provide an update of their medical records at the same time.

Read the detailed description

This protocol is designed to screen patients with suspected or identified genetic diseases of immune cell homeostasis, reflecting abnormalities in programmed cell death, survival, development, activation, and/or proliferation. Patients determined by clinical history and initial outside evaluation by their referring physician to be of interest will be consented and enrolled into this study. Blood and other biological specimens from patients or their family members will be obtained for research studies related to understanding the genetic and biochemical bases of these diseases. Outside medical records will be obtained for chart review to correlate clinical history to research laboratory testing results. Results will be relayed to the referring physicians and, where applicable, patients may be referred to other relevant research studies at the NIH.

The study will enroll up to 5000 patients and family members over the next 20 years.

Individual data sharing
No: If an individual requests to have their raw sequencing data, we have asked the IRB for permission. This has happened in one case. @@@@@@@@@@@@In another case during this reporting period, a subject asked us to share raw sequencing data with an academic center for analysis. This required a DTA which was recently completed.@@@@@@@@@@@@Sequencing is done under research conditions and is not shared with a subject unless it is verified with a repeat independent sample and CLIA certified.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 2 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 29 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 8 sites in Turkey (Türkiye), 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 Helen C Su, M.D. ((301) 451-8783, hsu@mail.nih.gov), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

determination of underlying susceptibility trait(s) and elucidation of its mechanism of action (time frame: 2030). 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 NCT00246857, which also lists 4 linked publications.

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 29 Oct 2026.
