Entire Body System
- Recurrent Infection
Its symptoms vary greatly between individuals but commonly include a history of recurrent infection, heart defects, and characteristic facial features. Few cases of DiGeorge syndrome have been reported in adults. [ncbi.nlm.nih.gov]
Seven (7) patients had recurrent infections, mainly pneumonia, and only one of them was free of any cardiac defect that might explain lung infections. Most infections occurred in the first year of life, before cardiac surgery. [scielo.br]
Recurrent infections begin soon after birth, but the degree of immunodeficiency varies considerably, and T-cell function may improve spontaneously. Hypocalcemic tetany appears within 24 to 48 hours of birth. [msdmanuals.com]
- Short Stature
Physical examination was remarkable for short stature, hypertelorism, prominent forehead and nasal voice. [ncbi.nlm.nih.gov]

Typical facies with a prominent nose and retruded mandible, cleft palate, cardiovascular defects, learning disability, retarded mental development, and short stature. Elements of this syndrome are frequently present in the robin syndrome. [web.archive.org]
- Increased Susceptibility to Infections
The early onset of recurrent infections due to severe immunodeficiency is no longer the main clinical feature of DGS, because only patients with complete DGS have an increased susceptibility to infection. [scielo.br]
In the majority of individuals, this increased susceptibility to infections spontaneously rectifies, and is more or less normal during the course of the child’s preschool and school years. [socialstyrelsen.se]
- Pulmonary Valve Stenosis
The four defects include a ventricular septal defect (VSD), pulmonary valve stenosis, a misplaced aorta and a thickened right ventricular wall (right ventricular hypertrophy). [drugs.com]

The other infections in the first 6 months included 20 bacterial lung infections, 19 bacterial urine infections, 19 viral infections, 6 episodes of diarrhea associated with Clostridium difficile, and 5 yeast infections. [doi.org]

- High Arched Palate
This sSMC, der(22)t(11;22)(q23;q11), is related to Emanuel syndrome, which is characterized by severe mental retardation, microcephaly, failure to thrive, preauricular tag or sinus, ear anomalies, and cleft or high-arched palate [ 33 ]. [doi.org]

Strabismus was observed in 13% and amblyopia in 6%. While posterior embryotoxon was observed in 12%-32% of controls, the incidence in individuals with 22q11.2DS was almost as high as that seen in Alagille syndrome (89%) [ Krantz et al 1997 ]. [ncbi.nlm.nih.gov]

Neurologic
- Seizure
At the age of 13 years, he experienced a seizure for the first time. At this time, the calcium concentration was normal. An electroencephalogram (EEG) proved that the seizure was due to epilepsy. Antiepileptic medications controlled the seizure. [ncbi.nlm.nih.gov]
A large cohort study showed that 21% of the patients with chromosome 22q11.2 deletion syndrome (62/290) had seizures, and at least 68% (42/62) of the seizures were hypocalcemic in origin [ 8 ]. [dx.doi.org]

Treatment
Immune deficiencies should be considered when infections are severe, persistent resistant to standard treatment, or caused by opportunistic organisms. [ncbi.nlm.nih.gov]
Complete DiGeorge syndrome is fatal without treatment, which is transplantation of cultured thymus tissue or hematopoietic stem cell transplantation. [msdmanuals.com]
Management and treatment Treatment depends on the associated abnormalities. It may consist of heart and/or palate surgery, speech therapy, nasogastric feeding, calcium supplementation, and psychological therapy. [orpha.net]
Treatment modalities depend on clinical manifestations present in the individual patient. Management is symptomatic and generally follows typical practice for patients without the syndrome, for any given feature. [bestpractice.bmj.com]
Prognosis
The clinical features, diagnosis, management, and prognosis of patients with DGS are presented separately. [uptodate.com]
Prognosis The prognosis is variable and depends on the severity of the disease. The infant mortality rate is relatively low (~4%); in adults mortality is higher than that of the rest of the adult population. [orpha.net]
Prognosis The prognosis is variable; many infants with DiGeorge syndrome die from overwhelming infection, seizures, or heart failure within the first year. [healthofchildren.com]

Etiology
DiGeorge syndrome, velocardiofacial syndrome, cardiofacial syndrome) but are now known to be etiologically identical and are referred to as 22q11.2 DS. [orpha.net]
Recognition of this etiology can improve patient outcomes and prevent recurrences. [ncbi.nlm.nih.gov]
One gene that is commonly deleted and implicated in the etiology is TBX1. [web.archive.org]
Epidemiology
METHODS: Patients underwent standard clinical and epidemiological protocol and tests to detect heart diseases, facial abnormalities, dimorphisms, neurological or behavioral disorders, recurrent infections and other comorbidities. [ncbi.nlm.nih.gov]
This topic reviews the epidemiology and pathogenesis of DGS. The clinical features, diagnosis, management, and prognosis of patients with DGS are presented separately. [uptodate.com]
Summary Epidemiology The worldwide incidence is estimated at 1/2,000-1/4,000 live births. Clinical description 22q11.2 DS shows a variable clinical phenotype that can range from mild to severe. [orpha.net]

Pathophysiology
Here, we focus on recent advances in cardiac assessment, speech, immunology, and pathophysiology of velocardiofacial syndrome. [ncbi.nlm.nih.gov]

This work is expected to (a) elucidate the pathophysiology of the CNS manifestations of the 22q11.2 syndrome and yield a brain intermediate phenotype that will allow studies in small and atypical deletion individuals in an effort to define individual [clinicaltrials.gov]
Pathophysiology The pathophysiology involves an embryologic defect in the 3 rd and 4 th pharyngeal pouch development from which thymus and the parathyroid glands evolve. [immunoloji.uludag.edu.tr]
Prevention
The combination of preimplantation genetic diagnosis with fluorescence in-situ hybridization is recommended to prevent pregnancies with DiGeorge syndrome affected embryos in properly selected patients. [ncbi.nlm.nih.gov]
Although the goal to prevent infection and therefore increase life span in DiGeorge syndrome patients is improving, thymus transplantation requires the use of immunosuppressant drugs, to prevent transplant rejection. [oncofertility.northwestern.edu]
