Serum ionized calcium concentration should be measured pre- and postoperatively to avoid hypocalcemic seizures due to physical stress.

DiGeorge syndrome - Wikipedia

The close correlation of birth and vascular defects indicated that vascular dysgenesis may pathogenetically contribute to the birth defects. Regionally restricted developmental defects resulting from targeted disruption of the mouse sjndrome gene hox CC HPO: Variable; commonly congenital heart problemsspecific facial features, cleft palate [7].

Seizures are seen in some individuals and are most often, but not always, associated with hypocalcemia. The number of people affected has been expected to rise because of multiple reasons: One of these was familial with an asymptomatic carrier father.

Patients showed deviations mostly in the posterior part of the dorsum sellae, and patients had increased cranial base angles compared to controls. It can be used in post and pre-natal diagnosis of 22q Of the 3 affected offspring, one had coarctation of the aorta, one a ventricular septal defect, and one DGS.
