[Pericentric inversion of chromosome 9. Summary of the authors' results]

A review is given of our experience in the pericentric inversions of chromosome 9 (26 cases). We examine the relevance of this pericentric inversion in the phenotype of the carriers, the significance of pericentric inversions of chromosome 9 in infertility, and the occurrence of aneusomic recombinants. We also discuss the importance of pericentric inversions of chromosome 9 in the genetic counselling and their use as a family maker.
