HCV Database
HCV sequence database
 



To our users Please note that the HCV database site is no longer funded. We try to keep the database updated and the tools running, but unfortunately, we cannot guarantee we can provide help for using this site. Data won't be manually curated either.


Note: The new recommendations for HCV nomenclature have been published here. A summary of the new system is here.

Recently assigned geno/subtypes

* Assigned 'confirmed' status because enough unambiguous sequence information was provided.

The image below shows which regions are defined (meaning there is at least on sequence of that region in the database) for which geno/subtypes. The red colored bar indicates that the genotype is confirmed.
