DiGeorge Syndrome

When your child is diagnosed with a condition as complex as DiGeorge Syndrome, it's natural to have questions and concerns. What does it mean for your little one’s health, development, and future? While this journey may seem overwhelming at times, you’re not alone. With knowledge, support, and the proper care, you can help your child lead a fulfilling life.

This guide will cover everything you need to know about DiGeorge Syndrome, from its causes and symptoms to treatment and effective caregiving strategies, including pediatric home health.

What Is DiGeorge Syndrome?

DiGeorge Syndrome, or 22q11.2 Deletion Syndrome, is a genetic disorder that occurs when a small segment of chromosome 22 is missing. This deletion affects multiple systems in the body, often resulting in a wide range of health, developmental, and behavioral challenges. It’s one of the most common genetic deletion syndromes, occurring in approximately 1 in 4,000 live births. With DiGeorge Syndrome, the presentation can vary widely, meaning that while some children may have significant health issues, others may have only mild symptoms that go undiagnosed for years.

The name "DiGeorge Syndrome" comes from Dr. Angelo DiGeorge, who first identified the condition’s link to immune system issues in the 1960s. Today, it’s understood that this deletion can affect not only the immune system but also the heart, brain, and endocrine system, as well as physical development.

Symptoms of DiGeorge Syndrome

The symptoms of DiGeorge Syndrome vary significantly from person to person, even within the same family. While some children experience only mild issues, others may face more severe challenges that require ongoing medical attention. The following are some of the most common symptoms of DiGeorge Syndrome:

• Heart Defects: Congenital heart defects are one of the primary features of DiGeorge Syndrome. These may include ventricular septal defects, tetralogy of Fallot, or interrupted aortic arch. Heart problems are often detected soon after birth and may require surgery.
• Immune System Issues: The thymus gland, which produces T-cells for the immune system, may be underdeveloped or missing in children with DiGeorge Syndrome. This can lead to frequent and severe infections.
• Facial Differences: Subtle differences in facial appearance may be present, such as low-set or abnormally shaped ears, a small jaw (micrognathia), hooded eyelids, or a flat nasal bridge.
• Cleft Palate: A cleft palate, which is an opening in the roof of the mouth, or other palate-related issues can lead to feeding difficulties and speech problems.
• Developmental Delays: Many children with DiGeorge Syndrome experience developmental delays, particularly in motor skills, language, and cognitive abilities. Speech therapy, physical therapy, and educational support can address these challenges.
• Behavioral and Emotional Challenges: Children with DiGeorge Syndrome are more likely to experience anxiety, ADHD, autism spectrum disorder, and other mental health concerns. Early behavioral support can improve long-term outcomes.
• Low Calcium Levels (Hypocalcemia): The parathyroid glands, which regulate calcium in the blood, may not function properly, leading to low calcium levels. If not treated, this can cause muscle cramps, irritability, and even seizures.

It’s important to remember that not every child with DiGeorge Syndrome will experience all these symptoms. Early diagnosis and intervention can significantly improve outcomes.

Causes Of DiGeorge Syndrome

DiGeorge Syndrome is caused by a deletion of a small section of DNA on chromosome 22 at position 22q11.2. This deletion typically occurs randomly during the formation of reproductive cells, affecting either sperm or egg, or in early fetal development. In about 90% of cases, it is a "de novo," or new, mutation, meaning it occurs spontaneously rather than inherited from a parent. However, in about 10% of cases, the condition is inherited from a parent who also has the deletion.

Risk Factors for DiGeorge Syndrome

There are no known lifestyle, environmental, or behavioral risk factors for DiGeorge Syndrome. It can affect children of any gender, race, or ethnicity. If one parent has the 22q11.2 deletion, there is a 50% chance it will be passed on to their child.

Complications of DiGeorge Syndrome

Without proper management, DiGeorge Syndrome can lead to several complications, including:

• Chronic Infections: Immune deficiencies can lead to frequent bacterial, viral, and fungal infections.
• Growth and Developmental Delays: Delays in walking, talking, and learning are common, but with the right interventions, many children catch up over time.
• Heart Problems: Congenital heart defects may require one or more surgeries.
• Seizures: Low calcium can trigger seizures if not managed properly.
• Mental Health Issues: Anxiety, depression, and behavioral challenges may arise during childhood or adolescence.

Awareness of these potential complications allows families and healthcare providers to be proactive and implement early interventions.

Diagnosing DiGeorge Syndrome

Doctors who believe DiGeorge Syndrome may be present can recommend genetic testing to confirm the diagnosis. Here’s what the diagnostic process typically involves:

• Physical Exam: A doctor will assess for heart defects, facial differences, and developmental delays.
• Genetic Testing: The 22q11.2 deletion can be detected by chromosomal microarray analysis or a FISH (fluorescence in situ hybridization) test.
• Additional Tests: Blood tests may measure calcium levels, and imaging tests such as an echocardiogram may check for heart abnormalities.

Early diagnosis can help rule out other conditions and is crucial for effective treatment and support.

Treatment Options for DiGeorge Syndrome

While there is no cure for DiGeorge Syndrome, treatment focuses on managing symptoms, addressing health challenges, and improving the child’s overall quality of life. Each child’s treatment plan is tailored to their specific needs, as the symptoms and severity of the condition can vary significantly. Healthcare providers, including pediatricians, cardiologists, endocrinologists, immunologists, and developmental specialists, can work together to ensure comprehensive care. Here are the key components of a treatment plan for children with DiGeorge Syndrome:

• Heart Surgery: Heart defects are one of the most serious and immediate concerns in children with DiGeorge Syndrome. Depending on the nature and severity of the heart defect, surgery may be required to correct structural abnormalities such as ventricular septal defects (VSDs), tetralogy of Fallot, or interrupted aortic arch. These surgeries are typically performed during infancy or early childhood to ensure proper oxygen flow and heart function, reducing the risk of life-threatening complications.
• Calcium and Vitamin D Supplements: Calcium and vitamin D supplements are prescribed for children with low calcium to maintain healthy levels in the blood. This helps prevent symptoms like muscle cramps, seizures, and irritability. Ongoing monitoring of calcium levels is essential, as fluctuations can occur throughout childhood and adolescence.
• Immune System Support: The thymus gland’s underdevelopment or absence can lead to immune deficiencies, making children with DiGeorge Syndrome more susceptible to infections. Treatment may involve immune-boosting therapies or prophylactic antibiotics to reduce the frequency and severity of infections. In severe cases, a thymus or bone marrow transplant may be necessary to restore immune function. Families are often advised to avoid exposure to certain viruses and bacteria, and children with significant immune deficiencies may need to avoid live vaccines.
• Developmental Support: Children with DiGeorge Syndrome often experience delays in speech, motor skills, and cognitive development. Early intervention is critical for addressing these delays. Treatment may include:
  • Speech Therapy: Speech-language pathologists work with children to improve their articulation, communication, and feeding skills, especially if they have a cleft palate.
  • Occupational Therapy: Occupational therapists help children develop fine motor skills, self-care abilities, and independence in daily activities.
  • Physical Therapy: Physical therapists support the development of gross motor skills such as crawling, walking, and balance, helping children achieve developmental milestones.
• Behavioral and Mental Health Support: Children with DiGeorge Syndrome are at an increased risk for anxiety, ADHD, autism spectrum disorder (ASD), and other emotional and behavioral challenges. Behavioral therapy can address these issues by teaching coping strategies and promoting positive social interactions. Mental health support may also include family counseling, parent training, and, in some cases, medication to manage symptoms of anxiety, ADHD, or other mental health concerns.

By addressing each child’s specific needs, healthcare providers create a personalized care plan that evolves as the child grows. This comprehensive approach aims to improve the child’s physical health, cognitive development, emotional well-being, and overall quality of life.
