Prevalence and Incidence of Aromatase deficiency
Aromatase deficiency: Rare Disease
Aromatase deficiency is listed as a "rare disease" by the Office of
Rare Diseases (ORD) of the National Institutes of Health
(NIH). This means that Aromatase deficiency, or a subtype of Aromatase deficiency,
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 Aromatase deficiency as a "rare disease".

About prevalence and incidence statistics:
The term 'prevalence' of Aromatase deficiency usually refers to the estimated population
of people who are managing Aromatase deficiency at any given time.
The term 'incidence' of Aromatase deficiency refers to the annual diagnosis rate,
or the number of new cases of Aromatase deficiency 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.
