dc.description | Background: DiGeorge anomaly, velocardiofacial syndrome and conotruncal anomaly face syndrome are part of a group of congenital malformations of the chromosome 22q11 microdeletion syndrome, since they share certain phenotypic features as well as a common genetic abnormality. The malformations include mild facial dysmorphic features, conotruncal heart defects, thymic and parathyroid hypoplasia or aplasia and cleft palate. Aim: To describe the initial clinical presentation of children with clinical and molecular diagnosis of 22q11 microdeletion. Patients and methods: Ten children (seven male) with the phenotypic features of 22q11 microdeletion syndrome are reported. Microdeletion was detected in peripheral Iymphocytes by fluorescent in situ hybridisation (FISH) with the TUPLE-1 DNA probe. Results: Two children had abnormal karyotypes, one of them had a visible deletion and another child had an unbalanced translocation inherited from his mother who had a balanced translocation between chromosomes 14 and 22. Two of the 10 patients had an anterior laryngeal web, a malformation infrequently described in this syndrome. Five patients had the diagnosis of DiGeorge anomaly, had a more serious clinical presentation and a higher early mortality. Conclusions: The high frequency of the 22q11 microdeletion syndrome, estimated at 1:5.000 newborns, and its variable presentations requires a high level of awareness for its early diagnosis and appropriate management of associated complications.
