We describe a child with a supernumerary chromosome defined as der(9)t(9;22) (q12;p11), resulting in trisomy 9p and trisomy 22p. The mother carried the balanced translocation. In G- and C-banding the derivative chromosome 9 appeared to be dicentric and to contain 22q material. Using in situ hybridiz

✦ Synopsis
We report on a fetus with cranio-facial anomalies, a narrow thorax, imperforate anus with cloacal cyst, and a genitourinary malformation with absent uterus, vagina, and external genitalia. Major thoracic defects were seen on roentgenographic examination, including absent vertebrae and ribs, a supernumerary vertebra, a hemivertebra, and rib fusion. These findings are compatible with Casamassima-Morton-Nance syndrome. The patient was the carrier of a translocation t(6;9)(p12;q12), inherited from the mother. Although the occurrence of this rearrangement may be coincidental, it may also indicate a possible locus for this autosomal recessive thoracic dysplasia.

We report on a male fetus with partial trisomy 2p21-2pter and monosomy 15q26-15qter due to t(2,15)(p21;q26). This fetus had a typical trisomy 2p phenotype including minor facial anomalies, musculoskeletal defects and two unusual findings: polydactyly and anencephaly. The observation of anencephaly a
