We retrieved from NCBI's Genes and Disease site the list of 85 human genetic disorders, categorized by the 16 body parts that they affect (downloaded 29 January 2007). To link candidate genes with the 85 diseases, we downloaded the dataset of a gene-disease map from NCBI's OMIM database (downloaded 3 January 2007) (5). Accordingly, 2374 genes were mapped to 85 human genetic disorders.
