DiGeorge Syndrome (DGS), also referred to as Velo-Cardio-Facial Syndrome (VCFS), is an immunodeficiency disorder characterized by various congenital abnormalities. It is characterized by hypocalcemia due to hypoparathyroidism, heart defects, and thymic hypoplasia or aplasia. This may be due in part to structural differences such as a cleft palate (a hole in the roof of the mouth) or to functional difficulties (either VPI or oral apraxia). You cant prevent it because it results from the sharing of genetic information during conception. Many people with DiGeorge syndrome who reach adulthood will have a relatively normal life span, but ongoing health problems can sometimes mean their life expectancy is a bit lower than usual. This may show up as low blood calcium on a routine blood test, or the infant may be jittery or have seizures as a result of the low calcium. It makes them susceptible to infections that DiGeorge syndrome presents with micrognathia, congenital heart disease, hypocalcemia, seizure, and cellular immunodeficiency because of anomalies in the thymus, parathyroid and great vessels [3]. The outlook for people with DGS depends on the function of each affected organ system.

For patients who do not have the 22q11 microdeletion, a DGS diagnosis can still be made on the basis of the characteristic combination of clinical features and by excluding a diagnosis of other syndromes. Some have major learning disabilities; others have none. [46], Genetic testing using BACs-on-Beads has been successful in detecting deletions consistent with 22q11.2DS during prenatal testing. The majority of patients with DGS have less severe or mild deficiencies. It was also able to detect smaller atypical deletions that are easily missed using FISH. Autoimmune disease occurs when the immune system inappropriately attacks its own body.

This article does not contain any studies with human participants or animals performed by any of the authors. Children often perform lower on speech and language evaluations in comparison to their nonverbal IQ scores. [7] It is autosomal dominant, meaning that only one affected chromosome is needed for the condition to occur. They may request special tests if they note issues such as seizures, unique facial features or blood tests that show low calcium levels. -, Fung WL, Butcher NJ, Costain G, et al.
