Fig. . The 22q.11.2 story can be likened to the old adage of a group of blind men trying to identify an elephant by each examining a separate part. Each man was accurate in describing his own area of interest, but none was able to see the big picture. Several conditions once thought to be separate are now known to be due to the 22q11.2 deletion.

Tricuspid atresia has not been reported in 22q11 microdeletions causing DiGeorge and velo-cardio-facial syndromes. We investigated the prevalence of 22q11 hemizygosity in 26 children with tricuspid atresia. Fluorescent hybridization with the Sc11.1 probe demonstrated a 22q11 microdeletion in 2 patie
We read with interest the paper by Leana-Cox et al. [1996] which reported on 5 families with recurrent Di-George/velocardiofacial syndrome and deletions of chromosome 22q11 (del22q11), and which reviewed the pertinent literature. The authors observed that up to 25% of del22q11 are inherited. Particu
We report on a new patient with deletion of 22q11 associated with hemophagocytic lymphohistiocytosis and a fatal outcome. She had minor facial anomalies and cardiac malformation corresponding to those described in del (22q11) syndrome, normal T and B cell function and NK activity; bone marrow aspira
Genetic syndromes associated with deletions at chromosome 22q11 generally have been diagnosed during childhood based on a constellation of physical features. To investigate a reported association of velocardiofacial syndrome with psychotic disorders in adults, we assessed subjects with DSM-IV schizo
We report on male monozygotic twins with 22q11.2 deletion and discordant phenotypes. The twins had twin-to-twin transfusion syndrome. Twin 1, the smaller of the pair, had Tetralogy of Fallot, a characteristic facial appearance, swallowing dysfunction, anal atresia, short stature, and mental retardat
