Representative profiles of the PB and LN samples of case 1. Array CGH results for case 1 are shown. (A) In the PB sample of case 1, regions of gain were detected. The log2 ratio of chromosome 3 was 0.53 (arrowhead). The log2 ratios of chromosomes 7 and 8 were the same as for chromosome 3 (dotted line). (B) In the LN sample of case 1, a log2 ratio imbalance was found. Log2 ratios among chromosomes 2, 3, 7, 8, and 9 differed. The log2 ratios of chromosome 3 and 7 were 0.41 (arrowhead and dotted line). Arrows show different log2 ratios: chromosome 2 = 0.10, chromosome 8 = 0.25, and chromosome 9 = 0.15.
