Figure 1 Characterizing the abnormal karyotype of the patient by comparative genomic hybridization (A), G banding (B), and fluorescence in situ hybridization (C).(A) The baseline (middle) ratio is 1.0. The left-sided shift indicates a ratio of 0.8 and the right-sided shift indicates a ratio of 1.2. The result suggested that the patient carried a Y chromosome fragment. (B) Chromosome G banding showed the minute difference between the long arm terminal of the two X chromosomes, but the abnormality could not be determined.(C) Fluorescence in situ hybridization analysis of the patient's metaphase showed a Y chromosome hybridization signal (green) present in the long arm terminal of the derivative X chromosome (triangle) by means of X (red)/Y (green) whole chromosome probes, and only a red signal was observed in the normal X chromosome (arrowhead).
