Overview
Worldwide, the incidence of 21-hydroxilase deficiency classic salt wasting type is 5 per 100,000 persons. Prevalence varies according to ethnicity and geographic area. Worldwide, the prevalence of congenital adrenal hyperplasia due to 21 hydroxylase deficiency ranges from a low of 3.57 per 100,000 persons in Chinese population to a high of per 100,000 persons with an average prevalence of 357 per 100,000 persons in Yupik Eskimos in Alaska. This disease usually affects individuals of the Ashkenazi Jews and Mediterranean race. The classic type affects approximately 1 in 16,000 live births. Non-classic type is one of the most common autosomal recessive disorders in humans and affects approximately 1 in 1000 individuals, but in up to 1–2% among inbred populations, such as Eastern European (Ashkenazi) Jews.[1]
Incidence for each region:
21-hydroxylase deficiency is more prevalent in some ethnic groups, particularly in remote geographic regions (e.g. Alaskan Yupiks).
Epidemiology and Demographics
Incidence
- Worldwide, the incidence of 21-hydroxilase deficiency classic salt wasting type is 5 per 100,000 persons.
- Worldwide, the incidence of 21-hydroxilase deficiency classic simple or non-salt wasting type is 16.6 per 100,000 persons.
- Worldwide, the incidence of 21-hydroxilase deficiency late onset type type is 100 per 100,000 persons.[2]
Prevalence
- Prevalence varies according to ethnicity and geographic area.
- Worldwide, the prevalence of congenital adrenal hyperplasia due to 21 hydroxylase deficiency ranges from a low of 3.57 per 100,000 persons in Chinese population[3] to a high of per 100,000 persons with an average prevalence of 357 per 100,000 persons in Yupik Eskimos in Alaska.
- The non-classic form is one of the most common autosomal recessive diseases. The prevalence of the non-classic form may differ from 1 in 1000 to 1 in 100, with the higher prevalence among Mediterraneans, Hispanics, and Eastern European Jews.[4][2]
Race
- Congenital adrenal hyperplasia due to 21-hydroxylase deficiency usually affects individuals of the Ashkenazi Jews and Mediterranean race.
- The Ashkenazi Jews to Mediterranean race ratio is approximately 1 to 3.[5][6]
Incidence for each region:
21-hydroxylase deficiency is more prevalent in some ethnic groups, particularly in remote geographic regions (e.g. Alaskan Yupiks). Disease incidence for each region mentioned below:[4][3][2]
