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

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