- Abstract
The chromosome 22q11 deletion syndrome may present with a variety of phenotypes. Its symptoms generally include a characteristic facial dysmorphisms and multiplex developmental disorders. Fluorescence in situ hybridization is the current method of choice for the diagnosis if typical multiple defects and/or symptoms are present. The authors present the history of two patients who were followed-up for minor anomalies and various developmental disorders for several years in the genetic counseling office of the authors, but definitive diagnosis was not established. However, when DNA samples of the two patients were recently tested with array comparative genome hybridization, a diagnostic method which has already been used in their institute for several years, the results indicated deletion of the 11.2 region on the long arm of chromosome 22 in both patients. The authors draw attention to the incidence and wide phenotypic spectrum of the chromosome 22q11 deletion syndrome, and show that its identification can be aided with the novel molecular cytogenetic method available in their laboratory.
