Prevalence and Incidence of Rett's syndrome

Prevalance of Rett's syndrome:

estimated 1 per 10,000 - 22,000 females suffer from Rett syndrome, Genetics Home Reference website ... see also overview of Rett's syndrome.

Prevalance Rate:

approx 1 in 10,000 or 0.01% or 27,200 people in USA [Source statistic for calcuation: "estimated 1 per 10,000 - 22,000 females suffer from Rett syndrome, Genetics Home Reference website" -- see also general information about data sources]

Rett's syndrome: Rare Disease

Rett's syndrome is listed as a "rare disease" by the Office of Rare Diseases (ORD) of the National Institutes of Health (NIH). This means that Rett's syndrome, or a subtype of Rett's 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 Rett's syndrome as a "rare disease". More information about Rett's syndrome is available from Orphanet

Incidence (annual) of Rett's syndrome:

1 in 10,000-15,000 live female births ... see also overview of Rett's syndrome.

Incidence Rate:

approx 1 in 10,000 or 0.01% or 27,200 people in USA [Source statistic for calcuation: "1 in 10,000-15,000 live female births" -- see also general information about data sources]

Incidence extrapolations for USA for Rett's syndrome:

27,199 per year, 2,266 per month, 523 per week, 74 per day, 3 per hour, 0 per minute, 0 per second. [Source statistic for calculation: "1 in 10,000-15,000 live female births" -- see also general information about data sources]

Prevalance of Rett's syndrome:

The syndrome affects approximately 1 in every 10,000-15,000 live female births, with symptoms usually appearing in early childhood between ages 6 and 18 months. (Source: excerpt from NINDS Rett Syndrome Information Page: NINDS)

    About prevalence and incidence statistics:

    The term 'prevalence' of Rett's syndrome usually refers to the estimated population of people who are managing Rett's syndrome at any given time. The term 'incidence' of Rett's syndrome refers to the annual diagnosis rate, or the number of new cases of Rett's 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. For more information see about prevalence and incidence statistics.
