Additional Information:

Diagnosis GeneReviews 22q11.2 deletion syndrome (22q11.2DS) is suspected in individuals with a range of findings including:...
Clinical Description GeneReviews Findings in 250 individuals (48% male; 52% female) with 22q11.2 deletion syndrome (DS) are summarized below [McDonald-McGinn et al 1999]. In unpublished data on an additional 750 individuals evaluated through a large multidisciplinary 22q11 deletion syndrome center, the percentages for the following findings remain the same [Author, unpublished data (2012)]. ...
Differential Diagnosis GeneReviews All of the findings appreciated in association with 22q11.2DS can also be found as an isolated anomaly in an otherwise normal individual....
Management GeneReviews Clinical practice guidelines for the evaluation and treatment of individuals with 22q11.2 deletion syndrome have been published [Bassett et al 2011 (click here for full text)]....
