There are no ethnic, economic, geographic or education criteria to be suffering from AT. Girls and boys are affected the same way.
In France
Two recent French studies statistics (see research ) suggests that there are currently about 150 cases in France of patients with AT. Given the life expectancy of these patients and unidentified cases, the average prevalence is approximately 1 / 100, 000, value considered valid throughout Europe.
Other countries
Figures:
- 1 / 300 000 in the United Kingdom according to AT Society. (english AT charity)
- 1/40 000 (in the USA) according to the americans of AT Children Project (US charity), maybe more if we consider all children, especially younger ones, who are deceased but have not been properly diagnosed.
These figures seem very different, varying by a factor of 10. However, the English estimate seems low taking into account that about 1% of the population is carrying the defective ATM gene and that it is recessive (see Transmission). The U.S. estimate seems a bit high but we do not know on what basis it references.
Note that these very low probabilities are significantly increased when inbreeding, and this for all the recessive diseases. It is obvious: there is a much stronger chance of finding the alteration of a gene within a family, so both in a man and a woman being relatives, even distant.
In all cases, these statistics are impressive at first sight and exacerbate feelings of loneliness. Are we really alone? ... Well not more in facing the disease (7000 identified rare diseases) than in considering medical research: there are 250,000 new cases of cancer each year in France and the ATM gene may play a role for some of them. Therefore, it is regularly under the microscope objectives of researchers ..
