Welcome to IthaMaps

IthaMaps is a global epidemiology database of heamoglobinopathies, illustrating published data on a dynamic global to regional map. Country-specific information on haemoglobinopathy-related policies, prevalence, incidence and overall disease burden is given, including relative allele frequencies of specific globin mutations in each country and/or region, dynamically linked to corresponding IthaGenes entries.

IthaMaps content was supported by partnership with the HVP Global Globin 2020 Challenge
