DiGeorge Syndrome

DiGeorge syndrome (22q11.2 deletion syndrome) is a genetic condition that occurs when your child is missing a piece of chromosome 22. The condition can affect many different areas of your child’s body. They may have unique facial features. DiGeorge syndrome is a lifelong disorder with no cure. But treatment can help manage your child’s symptoms.

DiGeorge syndrome (22q11.2 deletion syndrome) is a genetic disorder that can affect many parts of your child’s body.

DiGeorge syndrome is a genetic disorder that can affect many parts of your child’s body. A missing piece of chromosome 22 causes the condition. Common abnormalities associated with DiGeorge syndrome include a cleft palate, kidney anomalies and thymus gland issues. Most children also experience:

  • Heart issues
  • Other unique facial features
  • Weakened immune system
  • Developmental delays

The complications of DiGeorge syndrome (also known as 22q11.2 deletion syndrome, velocardiofacial syndrome or VCFS) can range from mild to severe. The most severe issues can be life-threatening. There’s no cure for the condition. The diagnosis may feel overwhelming. But treatment can help your child manage the symptoms of this lifelong disorder.

Symptoms and Causes

DiGeorge syndrome symptoms

Signs and symptoms of 22q11.2 deletion syndrome vary from child to child. Some children might not experience any symptoms of the condition. Others may have symptoms that affect several parts of their bodies. Your child may experience:

  • Heart problems
  • Immune deficiency
  • Distinctive facial characteristics
  • Cognitive issues

Heart problems

Children with 22q11.2 deletion syndrome may experience life-threatening heart problems, including:

Immune deficiency

A deletion on chromosome 22 can cause symptoms that affect the function of your child’s immune system. The condition puts them at a higher risk of getting infections. Immune deficiency symptoms may include:

  • Frequent infections
  • Low number of white blood cells that fight infections
  • Underdeveloped thymus, which produces infection-fighting white blood cells

Distinctive facial characteristics

DiGeorge syndrome facial features may include:

  • Cleft lip and palate
  • Hooded eyelids
  • Flat cheeks
  • A prominent nose
  • An underdeveloped chin
  • Ears with attached lobes

Cognitive issues

22q11.2 deletion syndrome can affect the function and development of your child’s brain. They may experience:

  • Attention-deficit/hyperactivity disorder
  • Autism spectrum disorder
  • Developmental delays, including in fine motor skills, speech and language
  • Learning disabilities
  • Intellectual disability
  • Mental health disorders

Other signs and symptoms

A deletion of part of chromosome 22 can cause other signs and symptoms, including:

  • Skeletal abnormalities, like short stature and spine curvature (scoliosis)
  • Hearing loss
  • Vision loss
  • Breathing difficulties
  • Lower-than-average levels of calcium in your child’s blood (hypocalcemia)
  • Kidney structure and function abnormalities
  • Endocrine system (hormone) function abnormalities
  • Feeding difficulties during infancy

DiGeorge syndrome causes

A missing part of chromosome 22 causes DiGeorge syndrome. Each chromosome in your child’s body holds thousands of genes. Genes are responsible for providing the instruction manual to help their body grow and function.

The term “22q11.2” gives the specific location on the chromosome where genes are missing. In this condition, they’re missing from segment 11 on the long arm (q) of chromosome 22. When your child is missing genes, their body doesn’t have the instructions it needs to develop as expected. This leads to the symptoms of DiGeorge syndrome, like developmental and cardiac defects.

Who does DiGeorge syndrome affect?

DiGeorge syndrome can affect anyone. That’s because 9 out of 10 cases occur as a result of a chance deletion on chromosome 22. This happens when the egg and sperm meet in the early stages of fetal development. It happens randomly. You didn’t cause this condition by anything you did before or during pregnancy.

In 1 out of 10 cases, people inherit 22q11.2 deletion syndrome from one biological parent who has the condition. This means they inherit it in an autosomal dominant manner. Only one copy of the chromosome from one parent is necessary for your child to get the condition.

Diagnosis and Tests

How doctors diagnose DiGeorge syndrome

Your pregnancy care provider may be able to make a 22q11 2 deletion syndrome diagnosis before your baby is born. They might find the condition on a prenatal ultrasound or through a prenatal test, like amniocentesis.

If they don’t find the condition before your baby is born, your child’s provider will likely diagnose it soon after birth. They’ll perform a physical exam and look closely at your child’s face, ears and eyes for signs of the condition. They may also request several tests.

Tests that are used

Your child’s healthcare provider may use the following tests to diagnose 22q11.2 deletion syndrome:

Management and Treatment

How is DiGeorge syndrome treated?

DiGeorge syndrome treatment depends on the symptoms and conditions that affect your child’s body, often involving multiple medical services. Velocardiofacial syndrome, sometimes referred to as VCFS, often requires a team approach. Treatment may include:

  • Antibiotics
  • Calcium supplements
  • Ear tubes or hearing aids
  • Speech, physical and occupational therapy
  • Hormone replacement therapy
  • Surgery to repair internal organ symptoms or a cleft palate
  • Medicine for neurological conditions
  • Special education programs to address learning challenges in school

When should my child see their healthcare provider?

In most cases, your child’s provider will diagnose DiGeorge syndrome when your baby is born or during early childhood checkups. Contact their provider if your child shows signs or symptoms of DiGeorge syndrome.

If your child has trouble breathing, call 911 (or your local emergency service number) or visit the emergency room immediately.

Outlook / Prognosis

What can I expect if I have DiGeorge syndrome?

DiGeorge syndrome is a lifelong condition without a cure. Your child’s outlook depends on the severity of their symptoms. Some of their symptoms could be life-threatening, especially if they affect their heart.

With ongoing treatment and support, adults with DiGeorge syndrome can live active and fulfilling lives.

What is the life expectancy of a person with DiGeorge syndrome?

Most people diagnosed with DiGeorge syndrome have a normal life expectancy with mild symptoms. Severe symptoms can lead to a shortened life expectancy without treatment.

A note from Cleveland Clinic

It may be overwhelming to learn that your newborn has a genetic condition like DiGeorge syndrome. Remember that their diagnosis isn’t a result of something you did as their parent. Rather, their genetic instruction manual didn’t get completely put together when they were developing.

Talk to your child’s healthcare provider about genetic counseling to learn more about your child’s diagnosis and how you can help them grow.
