Tangier disease: Rare Disease

Tangier disease is listed as a "rare disease" by the Office of Rare Diseases (ORD) of the National Institutes of Health (NIH). This means that Tangier disease, or a subtype of Tangier disease, affects less than 200,000 people in the US population.

Ophanet, who are a consortium of European partners, currently defines a condition rare when if affects 1 person per 2,000. They list Tangier disease as a "rare disease". More information about Tangier disease is available from Orphanet

About prevalence and incidence statistics:

The term 'prevalence' of Tangier disease usually refers to the estimated population of people who are managing Tangier disease at any given time. The term 'incidence' of Tangier disease refers to the annual diagnosis rate, or the number of new cases of Tangier disease diagnosed each year. Hence, these two statistics types can differ: a short-lived disease like flu can have high annual incidence but low prevalence, but a life-long disease like diabetes has a low annual incidence but high prevalence. For more information see about prevalence and incidence statistics.
