This National Cancer Institute directory lists professionals who provide services related to cancer genetics (cancer risk assessment, genetic counseling, genetic susceptibility testing, and others).

This database provides software to assist with differential diagnosis in familial cancer. It is free but requires registration, downloading and installation of the software and data.

A new human gene map from the International RH Mapping Consortium. Each chromosome is displayed with RH Map GB3 and GB4, the genetic map, gene density and a cytogenetic ideogram.

This database is made up of 3 parts, the Somatic Mutation Database, the Germline Mutation Database and a List of Common Polymorphisms. The Somatic Mutation Database contains exclusively p53 mutations associated with human cancers that have been identified by sequencing and published in the peer-reviewed literature. The Germline Mutation Database contains information on families fulfilling the definition of Li Fraumeni and Li Fraumeni-related syndromes and on individuals carrying a germline mutation in the TP53 gene. The list of polymorphisms is a simple table that describes the DNA sequence variants (polymorphisms) that have been observed in the human population.

Serial Analysis of Gene Expression (SAGE) SAGEmap is a SAGE data resource for the query and retrieval and analysis of SAGE data from any organism. The data can be searched by tag, by sequence, by gene, by library and by Request Id.
