Worldwide distribution of most common ATTRv genotypes by country/region. Countries and regions with relatively high levels of TTR pathogenic variants noted in the text are represented by different colors. Each TTR variant is designated by its traditional nomenclature. Most TTR variants have even more regional heterogeneity in these countries and regions. ATTRv: hereditary transthyretin amyloid; TTR: transthyretin
