Interstitial deletions are relatively rare chromosomal anomalies that usually arise de novo. The data describing the phenotype associated with interstitial deletions of 5q are very limited. We describe the first case of multiple fetal anomalies, diagnosed on prenatal sonographic examination, associa

โฆ Synopsis
We report on a patient with de novo interstitial deletion of the long arm of chromosome 12: 46,XY,del(12)(q24.31q24.33). To our knowledge this is the first patient with this chromosomal abnormality reported. He was born with minor anomalies, ambiguous genitalia, tracheomalacia, and he was developmentally delayed at age 9 months. The phenotype associated with this deletion may be characteristic. However, because of the absence of reported cases of other patients with loss of this chromosomal region, we cannot delineate the specific phenotype further. Ambiguous genitalia or hypogonadism has been reported in other patients with chromosomal rearrangements involving 12q24.

We report on a girl with a phenotype and developmental profile initially suggestive of Angelman syndrome. Subsequently she was shown to have an interstitial deletion of the long arm of chromosome 17; [del(17)-(q23.1q23.3)], the smallest unique cytogenetic deletion in this region documented to date.
