What is 22q11.2 deletion syndrome in children?
22q11.2 deletion syndrome (22q11.2DS) is a genetic disorder. In children with this syndrome, a tiny piece of chromosome 22 is missing. This can cause many health problems. These problems may range from heart defects and developmental delays to seizures. The child may also have changes in how the eyes, nose, or ears look. Or the child may have an opening in the roof of the mouth (cleft palate). Most children with the syndrome only have some of the health problems. In general, any of the health problems can be treated, especially if they are found early.
The name of the syndrome refers to the missing piece of chromosome 22. It is located at a place on that chromosome called q11.2.
The symptoms of 22q11.2DS can vary greatly from one child to another. For that reason, several disorders caused by 22q11.2DS have had other names in the past. These names include:
- DiGeorge syndrome
- Velocardiofacial syndrome (VCFS)
- Shprintzen syndrome
- Conotruncal anomaly face syndrome (CTAF)
- Sedlackova syndrome
- CATCH 22 syndrome
Some children with the syndrome had been diagnosed with Opitz G/BBB syndrome or Cayler cardiofacial syndrome in the past. Healthcare providers now know that these disorders all share the same genetic cause as 22q11.2DS.
About 1 in 4,000 people have 22q11.2DS. But some experts believe this number is higher. Some parents who have a child with this chromosome problem may not know it because the symptoms are less severe.
What causes 22q11.2DS in a child?
Most children with 22q11.2DS are missing about 50 genes. Researchers don’t yet know the exact function of many of these genes. But missing the gene TBX1 on chromosome 22 likely causes the syndrome’s most common physical symptoms. These include heart problems and cleft palate. The loss of another gene (called COMT) may also explain the higher risk for behavior problems and mental illness.
About 9 in 10 cases of 22q11.2DS happen by chance (randomly). They occur when the egg is fertilized. Or they occur early in a baby’s growth in the mother’s uterus. This means that most children with the disorder have no family history of it.
But a person with the condition can pass it on to his or her children. About 1 in 10 cases are inherited from the mother or the father. When the condition is inherited, other family members could also be affected. A person who has this chromosome deletion has a 1 in 2 chance of passing the problem to a child. So both parents can have their blood studied to look for the deletion.
Which children are at risk for 22q11.2DS?
A child is more at risk for this disorder if he or she has a parent with the condition or is carrying the faulty chromosome. But most cases occur randomly.
What are the symptoms of 22q11.2DS in a child?
Symptoms of 22q11.2DS may vary widely, even among family members. At least 30 symptoms have been seen with this disorder. Most children have only some of the symptoms.
The most common symptoms include:
- Heart defects. These are usually present from birth (congenital).
- Mouth problems. These include cleft palate and a palate that does not close fully (velopharyngeal insufficiency). These can cause speech problems.
- Ear problems. This includes middle ear infections or hearing loss.
- Low levels of calcium in the blood. This is caused by problems with the parathyroid glands and can trigger seizures.
- Immune system problems. These can increase the risk for infections.
- Spine problems. These include curvature of the spine (scoliosis) and problems with the bones of the neck or upper back.
- Learning problems. These include delays in development and speech.
- Communication and social problems. This includes autism.
- Increased risk for mental illness. This includes anxiety, depression, or schizophrenia in adulthood.
- Feeding difficulties. These may occur because of a cleft palate, gastroesophageal reflux, or other issues.
- Kidney problems. These may include an abnormally shaped kidney or a missing kidney.
Facial features of children may include:
- Small ears with squared upper ear
- Hooded eyelids
- Cleft lip, cleft palate, or both
- Uneven (asymmetric) face when crying
- Small mouth, chin, and side areas of the tip of the nose
The symptoms of 22q11.2DS can be like other health conditions. Make sure your child sees his or her healthcare provider for a diagnosis.
How is 22q11.2DS diagnosed in a child?
Your child’s healthcare provider will look at your child’s prenatal history and complete health and family history. He or she will do a physical exam. Your child may need certain tests. These may include:
- Blood tests. These are to look for immune system problems.
- X-ray. This test makes pictures of internal tissues, bones, and organs.
- Echocardiography. This test looks at the structure of the heart and how well it is working.
- Fluorescent in situ hybridization (FISH) studies. This blood test looks for certain genes that are deleted. If the FISH test doesn’t find any deletion in the 22q11.2 region of the chromosome, but your child has signs of the syndrome, he or she will usually need a full chromosome study. This will look for other chromosome problems.
- Chromosomal microarray. This is similar to a FISH test. But it looks at many regions across all the chromosomes, including chromosome 22. This is to find a missing piece in the 22q11.2 location.
How is 22q11.2DS treated in a child?
There is no cure for 22q11.2DS. But many of its related health problems can be treated. You can help your child by seeking early care.
Treatment will depend on your child’s symptoms, age, and general health. It will also depend on how severe the condition is.
Treatment may include working with specialists. This may include any of the below:
- Cardiologist. He or she will look at any heart defects. The cardiologist may correct them with a procedure or surgery.
- Plastic surgeon and speech pathologist. They will look at any cleft lip or cleft palate defects.
- Speech and digestive specialists. They will look at any feeding problems. Some children with the syndrome have severe feeding problems. They need tube feedings in order to get enough nutrition.
- Immune system specialist. Your child should be checked by this type of specialist. If your child has a T cell problem, he or she is at risk for infections that keep coming back. Your child should not have any live viral vaccines. Your child should have any blood products for a transfusion irradiated. This is true unless your child’s immune system doctor says that is not needed.
Other common problems that may need treatment include:
- Low calcium. This is common in children with the syndrome, especially right after birth. But it can also happen during times of stress, such as during puberty or after surgery. Your child may need to take calcium and vitamin D supplements. Your child may need to see an endocrinologist. This is a doctor who specializes in treating problems of the endocrine system.
- Development problems. Young children with 22q11.2DS may be slow to meet developmental milestones. These include sitting, walking, and talking. The International 22q11.2 Deletion Syndrome Foundation recommends that parents consider physical therapy (PT), occupational therapy (OT), and speech therapy for their child. PT strengthens large muscles and helps children meet developmental milestones. OT focuses on small muscles used for tying shoes, buttoning clothes, and other tasks. It can also help with feeding problems. Speech therapy can help your child with language delays.
What are the possible complications of 22q11.2DS in a child?
A small number of children with severe heart defects and immune system problems caused by 22q11.2DS will not survive the first year of life. But most children with the syndrome who get treatment will survive and grow into adulthood. These children will likely need extra help throughout school. They may also need long-term care for their health needs.
Some children with the syndrome may have behavioral conditions. These include autism, attention deficit disorder, obsessive compulsive disorder, or anxiety.
How can I help prevent 22q11.2DS in my child?
Most cases of 22q11.2DS occur randomly. So the disease can’t always be prevented. In about 1 in 10 cases of the syndrome, the deletion is inherited from one of the parents. Think about having genetic testing and counseling to find out if this disorder is inherited. If you have the 22q11.2 deletion, you have a 1 in 2 chance of passing it on to a child. This is true for every pregnancy you have.
How can I help my child live with 22q11.2DS?
Most health problems caused by 22q11.2DS can be treated, especially if they are found early. You can help your child by:
- Keeping all appointments with your child’s healthcare provider.
- Calling the healthcare provider if you are concerned about your child’s symptoms.
- Telling others of your child’s condition. Work with your child’s healthcare provider and school to come up with a treatment plan.
- Thinking about getting genetic testing and counseling to understand whether 22q11.2DS is an inherited condition in your family.
When should I call my child’s healthcare provider?
Call the healthcare provider if your child has:
- Symptoms that don’t get better, or get worse
- New symptoms
Key points about 22q11.2DS in children
- 2 deletion syndrome (22q11.2DS) is a genetic disorder where a tiny piece of chromosome 22 is missing.
- Most cases happen randomly as a baby grows in the mother’s uterus. It can also be inherited.
- Symptoms vary widely and can range from heart defects and developmental delays to seizures. A child’s eyes, nose, or ears may look different. Or the child may have an opening in the roof of the mouth (cleft palate).
- The syndrome has no cure. But many related health problems can be treated. You can help your child by seeking early care.
- Most children who get treatment early will survive and grow into adulthood. They will likely need extra help throughout school. They may also need long-term care for their health needs.
- A person with this condition has a 1 in 2 chance of passing the problem to a child. So genetic testing and counseling are important.

Overview of The Syndrome Missing Genetic Pieces
by Sherry Baker-Gomez
The author, Sherry Baker-Gomez, is the parent of a child with VCFS. Her son, now 25, was finally diagnosed with VCFS at 18 years of age after a long medical history and searching for answers. Sherry, herself, had been so desperate for answers after many years of struggling with her son’s undiagnosed disorder that she became a nurse in an effort to understand the symptoms she saw in him and what they meant. Then she realized that many other parents needed answers and needed to know where to turn, so she began writing.
Committed to VCFS education, Sherry started gathering information on resources and, stories that offered support. Working along with other parents and professionals, Sherry has organized this collection of information into a comprehensive handbook that brings information and resources to parents, professionals, and others under one cover.

Footprints of Hope: VCFS (Velo-Cardio-Facial Syndrome)
by Raymond Tanner
54-year-old Raymond Tanner has always felt different. As a child, he looked unusual, had trouble speaking clearly and was a slow learner. Over the years, he’s had countless operations to improve his appearance. For Tanner, being diagnosed with VCSF (at the age of 43) helped him re-evaluate his life, but it also brought a burden of guilt – both his sons were born with the syndrome. His first son died of heart problems when he was nine days old. His other son, Andrew, has ongoing health issues. Tanner now hopes to help other families through giving them a better understanding of VCFS, and encouragement that support is available and there is hope for the future.
This book is a compilation of stories from families from Australia, France, Israel, New Zealand, South Africa, the UK and the USA; and other important information. It also tells about Raymond Tanner’s life story with VCFS in himself and his two sons.

Adolescence and Young Adulthood Being Different: Growing up with impairments
by Daniella Krijger
Daniella is worried about the future of her son Tijn. He has been diagnosed with 22Q11deletion syndrome, and also has ADHD, autism spectrum disorder and Dyslexia. She wanted to know how people with a syndrome, disorder or impairment led their lives, what they had been through and whether they had been able to make their dreams come true despite these obstacles. How does it feel when others see you as being ‘different’ and treat you ‘differently’?
In this inspiring book, adolescents and adults with 22Q11 deletion syndrome, ADHD and ASD tell about their dreams and ambitions, friendships, love, education, work, drugs and depressions. Young people with a disability have to work harder at doing their best. They have the additional challenge of biases and incomprehension. Increasing awareness about 22Q11 deletion syndrome will hopefully contribute to more understanding and patience for these people who might seem different but who are as ordinary as anyone else.

A Different Life
by Quinn Bradlee
Ten percent of the population is affected by a learning disability, but few of us understand what being learning disabled (LD) is really like. When he was fourteen, Bradlee was diagnosed with Velo-Cardio-Facial-Syndrome (VCFS), a wide-spread, little-understood disorder that is expressed through a wide range of physical ailments and learning disabilities. In this funny, moving, and often irreverent book, Bradlee tells his own inspirational story of growing up as an LD kid—and of doing so as the child of larger-than-life, formidably accomplished parents: long-time Washington Post executive editor Ben Bradlee and bestselling author Sally Quinn. From his difficulties reading social cues, to his cringe-worthy loss of sexual innocence, Bradlee describes the challenges and joys of living “a different life” with disarming candor and humor. By the end of A Different Life he will have become, if not your best friend, one of your favorite people.

Views from Our Shoes: Growing Up with a Brother or Sister with Special Needs
by Donald Joseph Meyer
In Views From Our Shoes, 45 siblings share their experiences as the brother or sister of someone with a disability. The children whose essays are featured here range from four to eighteen and are the siblings of youngsters with a variety of special needs, including autism, cerebral palsy, developmental delays, ADD, hydrocephalus, visual and hearing impairments, Down and Tourette syndromes. Their personal tales introduce young siblings to others like them, perhaps for the first time, and allow them to compare experiences. A glossary of disabilities provides easy-to-understand definitions of many of the conditions mentioned.
