Welcome to HepSeq
The aim of this initiative is to develop a web-accessible, quality-based, molecular, clinical and epidemiological database for hepatitis B infection as a tool for the research community and for those involved in hepatitis B case management. EM image of Hepatitis B, CfI Colindale
This database currently (Fri, 23 Mar 2018 11:25:53 +0000) has 1770 patient records and 2182 viral sequences.
Click here for more details on the current data.
The quality of all submitted sequences is checked.
We also provide tools:
to search database,
to genotype HBV strains (based on HBV surface antigen genes) and,
to annotate sequences for mutation known to be associated with anti-viral resistance and vaccine escape.
If you have any questions about the database, please email the curators.
This new web database development is funded by the UK Department of Health is curated and is hosted by the Health Protection Agency.
