Official Title: Studies of Disorders in Antibody Production and Related Primary Immunodeficiency States
Brief Summary:
This study investigates gene abnormalities in Primary Immune Deficiency(PID) with a goal of improving the diagnosis and treatment of patients.
The specific disorders include:
- X linked hyper IgM Syndrome which is caused by an abnormality in the CD40L gene.
- NEMO associated immune deficiency which is caused by an abnormality in a gene called NEMO.
- Common variable immunodeficiency (CVID) which has an unknown genetic basis.
- Other disorders of immunoglobulin production.
This study will:
- Better characterize the clinical features of CD40 L deficiency and NEMO associated immune deficiency and other related primary immune deficiency syndromes.
- Determine the frequency of CD40 L and Nemo abnormalities.
- Determine whether particular abnormalities in these genes are associated with more of less severe illness or with specific symptoms.
- Explore the basic mechanism by which these altered genes cause immune dysfunction.
- Identify other genes causing low immune globulin levels and related primary immune deficient states.
