Fig. (1) Chromosome idiograms depicting chromosomes involved in rearrangements. A) Aberrant chromosomes in the papillary thyroid cancer cell line TPC-1 with t(1;10;21) (1pter>1q31::21q22.1>21qter; 10q11.2>10pter::1q31>1qter; 21pter>21q22.1::10q21.2 >10q11.2::10q21.2>10qter). B) The approximate locations of the translocation breakpoints in our patient carrying a balanced t(4;10)(q33;q23). Arrows indicate the breakpoints.
