The sequencing result showed that in all the 22 samples, only 2 samples of lung cancer tissue express the isoform A of WT1 gene, others were stably expressing the isoform C of the WT1 gene, and no mutations and/or deletions were detected from exon 1 to exon 10, Figure 1 shows one of the sequencing result. This evidence concerns the gene WT1 and lung carcinoma.
