Fetus with Casamassima-Morton-Nance syndrome and an inherited (6;9) balanced translocation.

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.
