Pediatrics. Patients with a small thymus produce fewer T-lymphocytes than those with a normally sized thymus. Some infants who do not have a thymus or have an underdeveloped thymus have mothers who are diabetic. DiGeorge syndrome is the highest known genetic risk factor for psychosis, and one of many known genetic risk factors for autism. Patients who have initially been deemed immunocompetent but then develop frequent, severe or unusual infections should have their immune system reevaluated. 2.

It is due to chromosomal defects that arise early in gestation. We are moving forward with all of my specialist appointments to determine the range of my syndrome. The thymus controls the development and maturation of one kind of lymphocyte, the T-lymphocyte, T for Thymus. (See chapter titled The Immune System and Primary Immune Deficiency Diseases.) The size of the thymus affects the number of T-lymphocytes that can develop. After the nave T cells fight an infection, they lose the special markers and are called memory T cells. Sleep disordered breathing, including obstructive sleep apnea is seen in about 50% of patients with 22q in craniofacial clinic compared to about 11% in the general population. [2] 2013;8:E119-126.
