For anyone Curious: 22Q/Digeorge Syndrome is a disorder caused when a small part of chromosome 22 is missing, this results in slower development of the body, though symptoms can vary, a person with 22Q may suffer learning difficulties, behavioural problems, may develop speech/movement at a slower rate, may have a cleft palate and have problems . However, many patients with DiGeorge syndrome have mothers with diabetes. The term 22q11.2 deletion syndrome covers terms once thought to be separate conditions, including DiGeorge syndrome, velocardiofacial syndrome and other disorders that have the same genetic cause, though features may vary slightly. Depending upon the functions of the particular protein, this can affect many organ systems of the body. Specialty clinics that provide multi-system care allow for individuals with DiGeorge syndrome to be evaluated for all of their health needs and allow for careful monitoring of the patients. By definition, complete DiGeorge syndrome is characterized by absence or underdevelopment (hypoplasia) of the thymus resulting in very low T cell counts. In a small number of cases, DiGeorge syndrome is hereditary (passed from a parent to a child). Infants with complete DiGeorge syndrome have additional symptoms including congenital heart defects and/or hypoparathyroidism.

The defects are usually related to face, heart, and immune system abnormalities. [7][8], DiGeorge syndrome is typically due to the deletion of 30 to 40 genes in the middle of chromosome 22 at a location known as 22q11.2. This deletion results in the poor development of several body systems. [11] [12] In late 1981, the underlying genetics were determined. National Organization for Rare Disorders.

As part of the developmental defect, the thymus gland may be affected and T-lymphocyte production may be impaired, resulting in low T-lymphocyte numbers and frequent infections. Parathyroid hormone plays a role in regulating the levels of calcium and phosphorus in the blood. Approximately 90% of patients with DGS have a small deletion in chromosome number 22 at position 22q11.2.
