Figures & data

Figure 1.  Cytogenetic and FISH results of the carrier with balanced reciprocal translocation. A) Partial GTG-banding karyogram showing the t(3;6)(q21;q23) rearrangement. Arrows indicate the abnormal chromosomes. B) FISH analysis on methaphase chromosomes with three color DNA probes for centromeric region of chromosome 3 (CEP3) (red), chromosome 6 (CEP6) (blue), and 3qtel region (green). One green signal (3qter) and one blue signal (CEP6) on the same chromosome confirm the translocation between chromosome 3 and 6.
