Figure 1From: Genome wide analysis of DNA copy number neutral loss of heterozygosity (CNNLOH) and its relation to gene expression in esophageal squamous cell carcinomaPatterns of loss of heterozygosity and copy number variation in 30 ESCC samples for chromosome 3. Each row (numbered 1 - 30) represents an individual ESCC sample. Circles indicate the positions of SNPs showing LOH. SNP positions are color coded as follows: black indicates copy number neutral LOH; blue indicates LOH accompanied by copy number reduction; red indicates LOH with copy number gain. An ideogram of the chromosome is at the bottom of the figure.Back to article page
