Figure

  • Fig. 1 Karyotyping of peripheral blood cells using conventional G-banding revealed an extra X chromosome.

  • Fig. 2 FISH analyses using sex chromosome-specific probes to the α-satellite of the X centromere region (red signal) and satellite III of Yq12 (green signal) on a buccal smear specimen revealed 86% XXY and 11.5% XY. The remaining 2.5% of cells had an XX signal pattern, probably due to the artificial loss of 1 Y chromosome in the FISH procedure or true mosaicism with 3 cell lines.
