About this study

OBJECTIVES: I. Identify the molecular defects responsible for primary immunodeficiency disorders.

II. Explore the mutations within each syndrome to better understand the genetics of these disorders.

III. Study the function of the Wiskott-Aldrich syndrome proteins (WASP). IV. Design methods to identify carriers and for prenatal diagnosis. V. Explore new avenues for therapy.

Read the detailed description

PROTOCOL OUTLINE: Patients are studied systematically to determine the extent of their immune deficiency and to confirm a specific diagnosis. Patients with a known immunodeficiency syndrome are studied in detail to identify the gene mutation, to assess the effect of the mutation on the gene product, and to establish cell lines for further in vitro assessment of the genetic defect. The function of Wiskott-Aldrich syndrome proteins (WASP) in hematopoietic cells is studied.

Family members of patients with X-linked disorders are studied to identify carrier females.

Questions about this trial

What is this clinical trial studying?

An observational study of X-Linked Agammaglobulinemia and X-Linked Hyper IgM Syndrome, run by Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) 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?

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: status not confirmed, as of the sponsor's last update on 24 Jun 2005. 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00004341, which also lists 2 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 24 Jun 2005.
