The ITHANET Portal houses 4 interconnected databases: the haemoglobin mutation database, the HbF reactivator database, the genotype-phenotype database, and the frequency database. Currently the first two of these databases are up and running. The mutation database has detailed information on about 1500 known haemoglobin mutations, displayed on genomic sequence with advanced search and filtering capabilities. For medical experts and researches of the field, it is fairly straightforward to curate and expand this collection of haemoglobin mutations.
