Database Description

HOWDY is an integrated database system for accessing and analyzing human genomic information ( HOWDY stores information about relationships between genetic objects and the data extracted from a number of databases. HOWDY consists of an Internet accessible user interface that allows thorough searching of the human genomic databases using the gene symbols and their aliases. It also permits flexible editing of the sequence data. The database can be searched using simple words and the search can be restricted to a specific cytogenetic location. Linear maps displaying markers and genes on contig sequences are available, from which an object can be chosen. Any search starting point identifies all the information matching the query. HOWDY provides a convenient search environment of human genomic data for scientists unsure which database is the most appropriate for their search.

Recent Developments

HOWDY updated its batch search system and now return the search results by an e-mail showing the URL from which users can download (1) separate XML files, (2) a merged XML file, or by an e-mail (3) attached XML files. Chromosome map were also updated in that Y chromosome data were released.


We would like to thank Mika Hirakawa for her assistance. Thanks also go to Fujitsu Ltd for their programming support and database maintenance. This work has been supported by the Ministry of Education, Culture, Sports, Science and Technology (MEXT).
