Truncus arteriosus communis associated with chromosome 22q11 deletion.
OBJECTIVES The purpose of this study was to clarify characteristics of truncus arteriosus communis associated with chromosome 22q11 deletion (del 22q11). BACKGROUND DiGeorge syndrome and conotruncal anomaly face syndrome are associated with del 22q11 (hemizygosity). In 30% of cases, truncus arteriosus communis is associated with the deletion. METHODS Fifteen consecutive patients with truncu...
متن کاملIsolation of the subclavian artery associated with chromosome 22q11 deletion.
An interesting report on isolation of the subclavian artery appeared in the recent issue of this journal. The authors reported 3 patients with interruption of the aortic arch between the carotid arteries ('type B'), isolation of the subclavian artery, and deletion of the chromosome 22ql l . Isolation of the subclavian artery is a rare anomaly. Although the authors discussed only briefly the eti...
متن کاملAbnormalities of the corpus callosum in nonpsychotic children with chromosome 22q11 deletion syndrome.
Chromosome 22q11 deletion syndrome (22q11DS) is associated with elevated rates of schizophrenia and other psychoses in adulthood. Childhood morphologic brain abnormalities are frequently reported, but the significance of these and their relationship to the development of schizophrenia are unclear. We sought to delineate midline neuroanatomical abnormalities in nonpsychotic children with 22q11DS...
متن کاملMonozygotic twins with chromosome 22q11 deletion and discordant phenotype.
We report monozygotic twins concordant for 22q11.2 deletion but discordant for clinical phenotype. Both boys show the typical dysmorphic features with short palpebral fissures, square nasal tip, small mouth, and both have nasal speech, but only one twin had a heart defect. They show that the phenotypic variability seen in this microdeletion syndrome cannot be explained on the basis of genotypic...
متن کاملConotruncal anomaly face syndrome is associated with a deletion within chromosome 22q11.
The conotruncal anomaly face syndrome was described in a Japanese publication in 1976 and comprises dysmorphic facial appearance and outflow tract defects of the heart. The authors subsequently noted similarities to Shprintzen syndrome and DiGeorge syndrome. Chromosome analysis in five cases did not show a deletion at high resolution, but fluorescent in situ hybridisation using probe DO832 show...
