The clinical picture found in a child with trisomy 9p confirmed that this chromosomal syndrome is a entity, which arises from maternal translocation t(9;21).

Trisomy 9p with de novo 9/15 translocation and 9p isochromosome was observed in a mentally defective boy with typical clinical features for this syndrome. This chromosomal aberration is probably caused by the pericentric inversion of chromosome 9 of the patient's father.

We report on a female infant with partial trisomy 9p (pter→p13) and partial trisomy 14q (pter→q22) resulting from a 3:1 segregation of a maternal reciprocal translocation (9;14)(p13;q22). Both trisomy 9p and partial trisomy 14q have been described as recognized phenotypes with characteristic pattern

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
