Study summary

The immune system is an intricate system comprised of specialized cells, proteins, tissues and organs. Proper functioning is critical to the body's ability to defend itself against harmful pathogens. Immunological disorders and deficiencies are defects in the immune system that lead to abnormal immune responses. Abnormal immune responses could be derived from immune deficiencies, dysregulations or hypersensitivities.

The overall goal of this research study is to identify the mechanisms of primary immune deficiencies and immune disorders at the genetic, cellular and molecular level, using novel analytic techniques to be performed on immune cells derived from blood samples. The knowledge gained from the aims of this study could lead to better diagnostics and identify novel targets for therapeutic interventions.

Read the detailed description

Primary immunodeficiency diseases (PID) represent a class of disorders in which there is an instrinsic defect in the human immune system. The PID could be caused by defects or perturbations in either the innate or adaptive immune cells, such as B cell defects which result in lack of antibodies. Research in this topic remains a difficult feat due factors such as genetic heterogeneity and the gene-environment interface. Limitations of standard of care testing leads to many patients with immunological problems to be undiagnosed. In addition to the variety of primary immune deficiencies, there are large number of immune system disorders due to various perturbations in the immunological components that cause diseases with much greater prevalence such as autoimmune diseases, lymphoproliferative diseases, chronic inflammation and certain cancers. The causes of these immune disorders are typically more complex than PID but there are also many overlaps in immune hyper-activation and deficiency.

Study population

Patients with abnormal immune responses or potential PID or immune disorders (allergies, autoimmune diseases) will be enrolled as the study group and patients with no prior immune abnormalities will be enrolled as the control group.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Subject is greater than or equal to 1 day of age and less than or equal to 100years of age
  • Signed /Assent
  • Subject is able and willing to comply with study protocol requirements
  • From clinical or blood laboratory findings subject has evidence of immune abnormalities (or no immune abnormalities in the case of controls) or immune-mediated disease.

Exclusion criteria

Exclusion Criteria:

  • Risk factors for donating blood (such as anemia or blood clotting disorders)
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Tracking since Sep 25, 2026
Not marked actual or estimatedDates not marked actual or estimated

The record gives a start of Dec 2012, a primary completion of Dec 2018 and a completion of Dec 2018. It does not say whether these dates are actual or estimated.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 4, 2017, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
