[Partial trisomy 11 revealed by labeling technics].
A standard karyotype was normal in 1968, when performed in a girl with multiple malformations. The same investigation was performed 7 years later with labelling techniques. It showed a partial duplication of the short arm of chromosome no. 11. This emphasizes the interest of a second karyotype in clinically suggestive cases, if the first has been performed before labelling techniques were used.
