  2. * Source of population data as of 2003:
  3. ** Although it is a crude estimate, we used the prevalence of the specific population in the study and the total population in the country to extrapolate the absolute number of people with albinism within a country
  4. # OCA2 = Oculocutaneous albinism Type 2 (Tyrosine positive)
  5. + The absolute number in this case was estimated from a prevalence rate of 1 in 1,515 which was provided by the study's authors
  6. --- The population studied makes it difficult to generalize the prevalence to the entire country. Therefore, the absolute number within the country was not estimated
