DiGeorge Syndrome, now more commonly called 22q11.2 Deletion Syndrome, is a genetic condition that occurs when a small piece of chromosome 22 is missing. This deletion happens before birth and can affect multiple body systems, which is why people with this condition often experience a wide range of health challenges. The syndrome occurs in roughly 1 in 2,000 to 1 in 4,500 live births, making it far more common than many people realize.

The symptoms and severity vary dramatically from person to person. Some individuals have mild symptoms that barely affect daily life, while others face serious medical complications from childhood onward. Common issues include heart defects, immune system problems that make infections more frequent or severe, cleft palate, kidney problems, hearing loss, and developmental delays. Many people with DiGeorge Syndrome also experience learning disabilities, attention difficulties, or autism spectrum traits. Some develop psychiatric conditions like anxiety or schizophrenia during their teenage years or early adulthood.
When it comes to work, DiGeorge Syndrome creates unpredictable challenges. A person might manage a job successfully for months, then face a serious infection or hospitalization that interrupts their employment. Others struggle with the cognitive or developmental aspects—difficulty with executive function, social communication, or processing speed—that make traditional employment settings stressful. Some individuals require ongoing medical appointments and therapies that make maintaining a consistent work schedule nearly impossible.
The relationship between DiGeorge Syndrome and Social Security Disability Insurance (SSDI) hinges on whether the condition prevents someone from working. This is where understanding the medical evidence and documentation becomes crucial. The Social Security Administration doesn't simply look at the diagnosis itself; they examine what the condition actually prevents you from doing in a work setting.
Takeaway: DiGeorge Syndrome is highly variable. Before exploring disability programs, document exactly how your condition limits work—whether through medical records, specialist reports, hospitalization history, or functional limitations your doctors observe. This specific documentation matters far more than the diagnosis alone.
The Social Security Administration uses a five-step process to determine whether someone's condition prevents substantial work activity. Understanding this framework helps you see why certain medical information and documentation carry more weight than others when someone is considering whether to pursue disability benefits through SSDI or Supplemental Security Income (SSI).

The first step examines whether you're currently working and earning above a certain income threshold (called substantial gainful activity). If you're earning more than roughly $1,550 per month in 2024, Social Security generally assumes you can work, regardless of your diagnosis. This is a practical threshold—the agency recognizes that some people continue working despite serious conditions, and that continued employment can mean different things for different people.
Steps two through four involve an assessment of whether your condition is severe enough to prevent work. Social Security looks at medical evidence: test results, imaging studies, hospitalization records, treatment history, medication lists, and detailed notes from doctors who have treated you. For DiGeorge Syndrome specifically, this might include records from cardiologists (if you have heart involvement), immunologists (documenting infection patterns), speech-language pathologists (noting communication difficulties), psychologists (detailing cognitive or psychiatric issues), or developmental specialists (recording functional delays).
Social Security also considers your residual functional capacity—essentially, what work-related tasks can you still perform despite your condition? Can you sit for eight hours? Can you concentrate on detailed tasks? Can you handle stress? Can you be around other people without infection risk? Can you follow multi-step instructions? For someone with DiGeorge Syndrome, these answers depend heavily on their specific complications. A person with primarily cardiac involvement faces different limitations than someone whose main challenge is recurrent infections or cognitive delays.
The final step compares your remaining abilities to the actual demands of jobs that exist in the economy. Social Security considers whether there's any work you could do, not whether your specific job or preferred career remains available to you. This is a high bar—the administration must conclude that no substantial work exists that you can perform.
Takeaway: Social Security's evaluation is medical-evidence driven and function-focused, not diagnosis-focused. If you're considering disability programs, gather records from every specialist who has treated your DiGeorge Syndrome complications, and ask each doctor to write detailed notes about what you cannot do, not just what condition you have.
Social Security receives thousands of applications weekly. To stand out as someone whose condition genuinely prevents work, your medical file needs to tell a clear story. For DiGeorge Syndrome, this story is built from specific, contemporaneous medical records—not from a summary you write yourself or from outdated information.

The strongest documentation includes treatment records spanning several years, showing a pattern of your condition's impact. If you have cardiac involvement, cardiology reports with echocardiogram results, exercise tolerance data, and restrictions prescribed by your cardiologist carry significant weight. For immunological complications, records of actual infections (not theoretical risk), antibiotic courses, hospitalizations, immunoglobulin replacement therapy if you receive it, and your immunologist's written assessment of your infection risk all matter. If you have speech, language, or developmental delays, evaluations from speech-language pathologists and developmental specialists documenting your specific functional limitations become important evidence.
Psychiatric and psychological documentation is particularly valuable if DiGeorge Syndrome has led to anxiety, schizophrenia, or other mental health conditions—which happens in a meaningful percentage of people with this diagnosis. Psychological evaluations, psychiatric treatment records, medication trials and responses, and therapist or psychiatrist notes documenting how these conditions affect your daily functioning all carry weight. If you've had time off work due to psychiatric symptoms, hospitalization records strengthen the documentation significantly.
Hospitalization records are powerful evidence. They show that your condition reached a severity level requiring acute medical care. If you've been hospitalized for infections, surgical complications, psychiatric crisis, or cardiac issues, those records become part of your medical narrative and demonstrate that your condition isn't something you can manage and work through consistently.
School or employment records can also matter. If you attended special education programs, required accommodations, repeated grades, or left employment due to medical reasons, documentation of those facts supports the overall picture. A work history showing multiple job losses, frequent absences, or pattern of brief employment is circumstantial but contextual evidence that work has been difficult for you.
What doesn't help: self-written summaries of your condition, generic online information about DiGeorge Syndrome, or medical records more than five years old without recent follow-up. Social Security specifically asks doctors for statements about current functioning, which means your medical team needs to have seen you relatively recently and documented how your condition affects your present ability to work.
Takeaway: Request and organize medical records from every specialist who has treated your DiGeorge Syndrome complications during the past three to five years. Ask each provider to write a statement addressing how your specific complications limit your ability to work consistently. Hospitalization records, medication lists, and treatment failure histories are particularly persuasive.
Social Security offers two different disability programs, and they operate under different rules. Understanding which one might be relevant to your situation matters because the paths, the income limits, and the additional support services differ significantly.

Social Security Disability Insurance (SSDI) is a program for people who have worked and paid Social Security taxes. It's based on your own work history or, if you haven't worked, your parents' work history (if you became disabled before age 22). For someone with DiGeorge Syndrome diagnosed in childhood or early adulthood, if they haven't worked much or at all, SSDI based on their own record likely isn't available. However, if a parent has paid Social Security taxes and the person with DiGeorge Syndrome became disabled before turning 22, they may receive SSDI based on that parent's record. When that parent reaches retirement age or passes away, the benefits may continue or adjust. For adults with DiGeorge Syndrome who did work before their condition prevented continued employment, SSDI based on their own work record becomes relevant—and continues for life as long as medical evidence supports ongoing disability.
Supplemental Security Income (SSI) is a different program designed for people with disabilities who have limited income and resources. You
