Overview

The prevalence of albinism is estimated to be 1:17,000 to 1:20,000 in the general population.The Prevalence of different types of albinism varies and the most prevalent form is Oculocutaneous albinism 2 (OCA2).

Epidemiology and Demographics

Prevalence

  • The prevalence of albinism is estimated to be 1:17,000 to 1:20,000 in the general population [1] [2][3]
  • In the US, about 18,000 people have albinism
  • The Prevalence of different types of albinism varies
  • Oculocutaneous albinism 2 (OCA2) is the most prevalent form
  • The prevalence of different subtypes are as follows: [4]
    • OCA1 occurs in 1: 40,000 individuals worldwide; 70% of cases occurs in America and China
    • OCA2 occurs in 1: 39,000 individuals worldwide; this prevalence is estimated to be 1: 10,000 in African Americans, 1:36,000 in overall Americans, and 1:3,900 in Sub-Saharan Africa
    • OCA3 occurs in 1: 8500 individuals in Africa
    • OCA4 occurs in 1: 100,000 individuals; accounts for 24% of Japanese albinism
    • OCA5, OCA6, and OCA7 cases are very rare
    • Hermansky-Pudlak syndrome (HPS) occurs in 1: 500,000 population worldwide; the prevalence of HPS is 1:1800 in Puerto Rico
    • Chediak-Higashi syndrome (CHS) is very rare; less than 50 cases were identified in the last 20 years
    • Ocular albinism (OA1) occurs in 1:50,000 individuals

Age

  • As Albinism is a hereditary disease, it can be diagnosed from early ages of life

Race

  • There is no racial predilection to albinism
