Prevalence and Incidence of Thanatophoric dysplasia
Prevalance of Thanatophoric dysplasia:
1 per 20,000 - 50,000 newborns are affected by Thanatophoric dysplasia, Genetics Home Reference website ... see also overview of Thanatophoric dysplasia.
approx 1 in 20,000 or 0.00% or 13,600 people in USA [Source statistic for calcuation: "1 per 20,000 - 50,000 newborns are affected by Thanatophoric dysplasia, Genetics Home Reference website" -- see also general information about data sources]
Ophanet, who are a consortium of European partners,
currently defines a condition rare when if affects 1 person per 2,000.
They list Thanatophoric dysplasia as a "rare disease".

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