[Correlation of the clinical phenotype with a pericentric inversion of chromosome 9].
Pericentric inversion of chromosome 9 is one of the most common structural balanced chromosomal aberrations. It is considered as a paraphysiological variant of a normal karyotype and it is possible to find it as occasional report in healthy subjects. In the last ten years different signals have appeared in literature, concerning carriers of pericentric inversion of chromosome 9, who showed different anomalies of the clinical condition. Today it is difficult, because of the rarity of the data to establish if a true correlation exists between phenotypical anomalies in the subjects studied and the pericentric inversion, or if they are only casual associations. We are trying to find possible correlations between the chromosomal rearrangements and eventual congenital defects. We describe 11 subjects with pericentric inversion of chromosome 9 examined for the presence of dysmorphic signs, mental retardation and repeated miscarriage.
