Summary
CHARGE syndrome, a rare condition, is linked to T-cell immunodeficiency. Evaluating lymphocyte subsets in CHARGE syndrome patients is crucial for early detection and management of infections.
Area of Science:
- Immunology
- Genetics
- Pediatrics
Background:
- CHARGE syndrome is a complex genetic disorder with diverse clinical manifestations.
- An association between CHARGE syndrome and T-cell immunodeficiency is known but infrequently reported.
Observation:
- Four patients with CHARGE syndrome presented with moderate to severe T-cell lymphopenia and recurrent infections.
- Genetic analysis revealed CHD7 gene mutations in three of the four patients.
- None of the patients had 22q11.2 deletions, ruling out DiGeorge syndrome.
Findings:
- CHARGE syndrome is associated with a spectrum of T-cell immune deficiencies.
- Thymic hypoplasia is a potential clinical feature of CHARGE syndrome.
Implications:
- Routine lymphocyte subset analysis is recommended for all diagnosed CHARGE syndrome patients.
- Early identification of T-cell immunodeficiency can guide prompt treatment and improve outcomes.

01:25Immunodeficiency Diseases
Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.

01:22T Cell Activation and Clonal Selection
T cells are integral to our adaptive immune system, recognizing and effectively responding to foreign antigens. T cell activation and clonal selection are pivotal in orchestrating this immune response. This article elucidates these mechanisms, detailing the roles of cluster of differentiation (CD) markers, major histocompatibility complex (MHC) molecules, costimulatory signals, and the process of clonal selection.

01:24T Cell Types and Functions
When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.

01:27Cytotoxic T Cells-mediated Immune Response
Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...

01:27Cytomegalovirus Disease
Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...
