[Dwarfism in pericentric inversion of the X-chromosome].

We report on a 9 2/12 year old girl with pericentric inversion of the X-chromosome. It was diagnosed accidentally by a chromosome-analysis led through because of small stature. She bears a strong phenotypic resemblance to her mother (normal chromosomes), carrier of the pericentric inversion however is the phenotypically normal father. The breakpoint of the X-chromosome not lying within the critical region suggests that the patient will neither suffer a gonadal dysfunction. Both short stature and phenotypic dysmorphic features have familial cause.
