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

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