GeMap is a comprehensive database. At present, it integrates genome data of 27 different races that come from 18 countries, and collects data from six authoritative databases, including 38,659 genes and millions of mutation information. GeMap can provide data retrieval service. We can search in GeMap by using rs id, gene name, disease name and chromosome position, etc. In the future, GeMap will integrates disease repository, so that users can retrieve phenotype information with disease name, or retrieve related disease with gene name, etc. In addition, GeMap will build personal data analysis workstation, and then users can upload personal sequencing data, and get personal genome data analysis results. GeMap not only provides massive data support for the scientific researchers and medical practitioners, but also will provide the public with easy-to-use personal genome analysis tools and platforms, fully meet the needs of the masses.
