PARTIAL DIGEORGE-SYNDROME AT THE AGE OF 34

A 34-year-old man with partial DiGeorge syndrome suffered from seizure s and mental retardation from the age of three years. He was diagnosed as having primary hypoparathyroidism by the Ellsworth-Howard test at the age of 22. He was also found to have a right aortic arch. Immunolo gical studies revealed the presence of immature T cells (CD 38+, OKT 9 +), although the subsets and function of his T cells were almost norma l. The facts that the cardiovascular anomaly and immunodeficiency were mild and the hypoparathyroidism was well controlled, may account for his survival to this age.
