DiGeorge syndrome (22q11.2 deletion syndrome) Treatment in Hyderabad

overview

DiGeorge syndrome, more precisely known as 22q11.2 deletion syndrome, is a disorder caused by the absence of a small part of chromosome 22. This deletion leads to poor development of several body systems.

The term 22q11.2 deletion syndrome encompasses terms that were previously thought of as separate conditions, including DiGeorge syndrome, velocardiofacial syndrome, and other disorders that share the same genetic cause, although the characteristics may vary slightly.

Medical problems commonly associated with 22q11.2 deletion syndrome include heart defects, poor immune system function, cleft palates, complications due to low blood calcium levels, and developmental delays with behavioral and emotional problems.

symptoms

The signs and symptoms of DiGeorge syndrome (22q11.2 deletion syndrome) can vary in type and severity depending on the body systems affected and the severity of the defects. Some signs and symptoms may be felt at birth, but others may not appear until later in infancy or infancy. DiGeorge syndrome (22q11.2 deletion syndrome) Treatment in Hyderabad

Signs and symptoms can be a combination of the following:

The reasons

Every person has two copies of chromosome 22, one inherited from each parent. When a person has DiGeorge syndrome (22q11.2 deletion syndrome), one copy of chromosome 22 is missing in a segment that contains about 30 to 40 genes. Many of these genes have not been clearly identified and are not well understood. The deleted region of chromosome 22 is known as 22q11.2.

Deletion of genes from chromosome 22 usually occurs as an accidental event in the father’s sperm or mother’s egg, or can occur early in the development of the fetus. In rare cases, the deletion is an inherited disease passed from a parent to a child who also has deletions on chromosome 22 but may or may not show symptoms.

Complications

Heart defect. The 22q11.2 deletion syndrome often causes heart defects that can lead to an inadequate supply of oxygenated blood. For example, defects can include a hole between the lower chambers of the heart (interventricular communication); a single large vessel instead of two vessels emerging from the heart (truncus arteriosus); or a combination of four abnormal heart structures (Fallot tetralogy).

prevention

In some cases, DiGeorge syndrome (22q11.2 deletion syndrome) can be passed from an affected parent to a child. If you are concerned about a family history of 22q11.2 deletion syndrome, or if you already have a child with the syndrome, you should see a doctor who specializes in genetic disorders (geneticist) or a genetic counselor for you.
