Understanding DiGeorge Syndrome
DiGeorge syndrome, also known as chromosome 22q11.2 deletion syndrome, is a rare chromosomal abnormality that affects individuals from birth. It is caused by the deletion of a small piece of chromosome 22, specifically at position 22q11.2. This genetic mutation leads to a range of developmental abnormalities and health issues.
One of the most significant impacts of DiGeorge syndrome is T-cell deficiency, resulting in immunodeficiency. T-cells play a crucial role in the body’s immune response, helping to protect against infections and diseases. In individuals with DiGeorge syndrome, the absence or dysfunction of T-cells leaves them more susceptible to infections and other complications.
Genetic Basis and Diagnosis
The deletion of the 22q11.2 region disrupts the normal development of various organs and systems in the body, including the immune system. This abnormality can be detected through various genetic tests, such as fluorescence in situ hybridization (FISH) or chromosomal microarray analysis (CMA).
It’s important to note that the severity and symptoms of DiGeorge syndrome can vary from person to person. Some individuals may exhibit mild developmental issues, while others may experience more significant health challenges.
Impact on the Immune System
Due to the T-cell deficiency caused by DiGeorge syndrome, individuals are prone to recurrent infections, especially in the respiratory and gastrointestinal systems. Additionally, they may have reduced antibody production and impaired immune function overall.
