Angelman Syndrome – Epidemiology – Mature Markets

Clarivate Epidemiology's coverage of Angelman syndrome comprises epidemiological estimates of key patient populations across the major mature pharmaceutical markets (the United States, France, Germany, Italy, Spain, the United Kingdom, and Japan). We report the prevalence of Angelman syndrome for each country, as well as annualized case counts projected to the national population.

All patient populations are forecast for a period of 20 years for the major mature pharmaceutical markets.

Clarivate Epidemiology's Angelman syndrome forecast will answer the following questions:

  • How will demographic trends, such as population aging and improving life expectancy, affect the epidemiology of Angelman syndrome over the forecast period?

All forecast data are available on the Clarivate Insights Platform in tabular format, with options to download to MS Excel. All populations are accompanied by a comprehensive description of the methods and data sources used, with hyperlinks to external sources. A summary evidence table generated as part of our systematic review of the epidemiological literature is also provided for full transparency into research and methods. We report the following populations:

  • Diagnosed prevalent cases
  • Diagnosed prevalent cases by genotype
