Figure 1: (a) FISH results obtained using a DYZ3 probe (indicating that the patient has two Y centromeres). (b) FISH results obtained using SRY and DXZ1 probes (indicating that the patient has two short Y arms). FISH: fluorescence in situ hybridization; DYZ3: sequence in the centromeric region of chromosome Y; SRY: sex-determining region of Y-chromosome; DXZ1: alpha satellite sequence in the centromeric region of chromosome X.
