title: [Huntington's Disease in Balearic Islands Population-Based Registry of Rare Diseases: Prevalence and Mortality during the Period 2010-2013. Spain].
abstract: OBJECTIVE
  Huntington's disease is a hereditary disease with low prevalence. The low frequency of Huntington's disease leads to its inclusion as one of the pathologies in the Registry of Rare Diseases. The Balearic Islands Population-based Registry of Rare Diseases began in 2010. Previously, there had been no prevalence or mortality data for Huntington's disease in the Balearic Islands. The aim of this study was to determine the prevalence and mortality of Huntington's disease in the Balearic Islands between 2010 and 2013.
  
  
  METHODS
  The data sources were the Balearic Islands Population-based Registry of Rare Diseases, from which the diagnosed cases were obtained; the Balearic Islands Mortality Register, from which the deceased cases were obtained; the Balearic Islands Health Service, from which the number of Health Cards was obtained; and the National Institute for Statistics, from which population data were obtained. Prevalence and mortality rates were calculated.
  
  
  RESULTS
  The Balearic Islands Population-based Registry of Rare Diseases registered 27 cases of Huntington's disease between 2010-2013. 63% of these were women. The period prevalence rate was 2.6 per 100,000 and the period mortality rate was 1.1 per 100,000. Menorca was the island with the highest rates, the prevalence rate was 5,9 per 100,000 and the mortality rate was 2,1 per 100,000.
  
  
  CONCLUSIONS
  Prevalence and mortality of Huntington's disease in the Balearic Islands are low compared to similar areas.
