| syndrome, digeorge | This disorder is characterised by (1) low blood calcium levels (hypocalcaemia) due to underdevelopment (hypoplasia) of the parathyroid glands which control calcium; (2) underdevelopment (hypoplasia) of the thymus, an organ behind the breastbone in which lymphocytes mature and multiply; and (3) defects of the heart involving the outflow tracts from the heart. most cases of dgs are due to a microdeletion in chromosome band 22q11.2. A small number of cases have defects in other chromosomes, notably 10p13. Named after the american paediatric endocrinologist angelo more than digeorge. Other names for dgs include the third and fourth pharyngeal pouch syndrome and hypoplasia of the thymus and parathyroids. (12 Dec 1998) |

| DiGeorge s. |
a congenital disorder in which defective development of the third and fourth pharyngeal pouches results in hypoplasia or aplasia of the thymus and parathyroid glands, often associated with congenital heart defects, anomalies of the great vessels, esophageal atresia, and abnormalities of facial structures. Depending on the degree of parathyroid and thymic hypoplasia, there are hypocalcemic tetany or seizures due to lack of parathyroid hormone and deficiency of cell-mediated immunity resulting in increased susceptibility to low-grade or opportunistic pathogens. The chromosomal abnormality is a deletion of part of the long arm of chromosome 22, resulting in the loss of the T-box gene Tbx1. Called also thymic aplasia or hypoplasia and pharyngeal pouch s.
