MHC correlation plot. The y-axis shows the correlation between couples at each SNP. Positive correlation means that the SNP shows identity between couples; negative correlation means that the SNP shows dissimilarity between couples. The size of the points is proportional to the SNP-wise significance. The color of the points indicates the function of the SNP (from UCSC). The MHC region is a mosaic of positive and negative correlations. Classes I and II are shaded grey. Proposed MS-related genes are highlighted with red stars. Positions and gene symbols are from UCSC (build 36).
