Fig. 2From: Analysis of copy number variation at DMBT1 and age-related macular degenerationRegional association plots of DMBT1 copy number variation and flanking SNPs. Analysis of SNPs within the 1Â Mb region flanking DMBT1 and association with diploid copy number of a CNV1 and b CNV2. The left-hand y-axis shows statistical support for an association, as measured by the negative log10 of the p-value of the linear regression test of association. The right-hand y-axis shows the recombination rate inferred from HapMap population data. The index SNP is shown as a diamond, and is annotated with its rs number. The size of each point reflects the number of genotypes for that particular SNP, and the colour of each point reflects the strength of association with the index SNPBack to article page
