Mechanisms of Immune Deficiency

Immune Deficiency Clinical Trial

Official title: Mechanisms of Immune Deficiency

Status Recruiting

Clinical Trial Summary

1. The purpose of this study is to learn more about the changes in genes, cells and proteins that cause immune deficiency diseases.

2. The early stages of the study will focus on two groups of patients:

1. members of families in which several persons have symptoms or medical histories that suggest immune deficiency.

2. Patients who have received treatments with medications or drugs that affect functions of the immune system (secondary immune deficiencies).

It is hoped that studies will provide guidelines for extension of the research to other patient groups. Up to 200 patients and family members will be invited to participate.

Clinical Trial Description

The experiments that are proposed in this portion of the study are intended to:

1. characterize the significance of the variant form of EZH2 identified in this family. They will characterize the degree of methylation of lysine 27 of histone H3 in subjects with the variant and members of the same family who have the wild type gene. The functional methyltransferase activity of the variant and wild type genes will be measured.

2. characterize the current status of B-cell maturation and function in subjects with either the variant gene and the wild type gene.

3. characterize B-cell function (antibody production) and the quality of antibody produced after immunizations in subjects with the wild type gene or the variant gene. ;
