title: Lung hypoplasia in a patient with del(2)(q33-q35) demonstrated by chromosome microdissection.
abstract: We report on a 17-month-old girl with multiple malformations, including lung hypoplasia, multiple ventricular septal defects, craniofacial anomalies, and malrotation of the intestine. Moreover, the patient showed Robin sequence, developmental delay, as well as pre- and postnatal growth retardation. Postnatal cytogenetic analysis revealed an interstitial deletion on the long arm of chromosome 2. Microdissection and reverse chromosome painting of the aberrant chromosome 2 as well as FISH with a panel of chromosome 2q band-specific YACs mapped the deletion to 2q33-q35. Lung hypoplasia has not been described so far in patients with del(2)(q33-q35). A review of previously reported patients showed variable phenotypes apparently due to different deleted chromosomal segments.
