DiGeorge anomaly comprises hypoparathyroidism, thymic aplasia, conotruncal cardiac anomaly and dysmorphic features. Most cases result from a microdeletion within chromosome 22q11. We report a case of documented DiGeorge anomaly and the use of high resolution cytogenetic analysis and the fluorescence in situ hybridization technique are discussed.
Key words: DiGeorge Anomaly; In situ hybridization, fluorescence
