From: A disease similarity matrix based on the uniqueness of shared genes
A co-occurrence matrix showing the relationship between 1,854 diseases using DORIF data. Matrix elements colored blue indicate a relationship between two diseases, white elements indicate no relationship. Each blue matrix element (i, j) contains the sum of the uniqueness values for genes related to both disease i and disease j (i.e. d ij ), while white elements are equal to 0. Diagonal elements indicate the identity relationship for each disease, i.e., the sum of the uniqueness values for all genes associated with disease i . This figure was created using MATLAB [20]. The disease-gene relationships were extracted from DORIF data
