Figure 3From: Copy-neutral loss of heterozygosity and chromosome gains and losses are frequent in gastrointestinal stromal tumorsLocalization of allelic breakpoints as determined from the SNP array and QMPSF in the CDKN2A/CDKN2B genes. In case #3C2, #5C3 and #18C3, the copy number varied within this locus according to SNP analysis, and was confirmed by QMPSF. For QMPSF quantification, DMRTA1 was used as a control gene.Back to article page
