[Computer databases on cancer-related genes].

A database of mutations in various cancer-related genes has been constructed and named as KMcancerDB (Keio Mutation DataBase for cancer-related genes). This KMcancerDB utilizes a database software called MutationView which we designed to compile various mutation data and to provide graphical presentation of data analysis through the network using ordinary internet browser softwares such as Netscape. Currently, the KMcancerDB accommodates 1261 mutation data of different genes for cancers in 9 different organs/tissues (breast, stomach, uterus, liver, prostate, colon, ovary, thymus and retinoblastoma). KMcancerDB is accessible through http:¿mutview.dmb.med.keio.ac.jp. OMIM is an important document database for human Mendelian traits and hereditary diseases. The information from OMIM is also used in MutationView/KMcancerDB. Some display windows of OMIM and KMcancerDB are presented.
