Distribution of gene-disease associations. The Y-axis scale is logarithmic. a Number (#) of genes associated with diseases. 2672 diseases are distributed with respect to the number of associated genes. 2051 diseases are monogenic; 621 diseases are associated with multiple genes (from 2 to 69). b Number (#) of diseases associated to genes. 3658 genes are distributed with respect to the number of associated diseases. 2544 genes are associated with a single disease; 1114 genes are associated with multiple diseases (from 2 to 16)
