How to check DNA data for certain genes

Simple genetic testing services like those from 23andMe and Ancestry DNA provide you with raw genetic data, and this data can be opened and examined to see if you have certain gene variants or mutations, for instance those more likely to be found in people with ME/CFS, or for other issues like food sensitivities including lactose intolerance.

Get a DNA test

 * 1) Simple home based saliva tests are available from companies like 23andMe and Ancestry DNA, which provide results to an account the person create with them on the internet.


 * 1) The person spits into a tube and posts it, and some weeks later they are notified that their data is ready for them on the company's website.


 * 1) Companies typically profile some free analysis, such as which counties or areas your ancestors are most likely to have come from.


 * 1) There will be an option to download your "raw data". This is a very large, human readable and computer readable file. They advice you to keep it very secure. If you can't find the option for this look in the "Help" area on the website of the company that analysed your data.


 * 1) There are often options to pass more for a more detailed health report. Due to a lack of studies, the science is unclear with ME/CFS due to a limited number of studies, and very recent studies may not be included, so this may not be what you might hope for. It may cover well-known illnesses with a genetic link such as breast cancer or Parkinson's disease.

Understanding the raw data
Each gene variant or mutation has an ID number assigned to it, beginning with rs, e.g., rs4988235.
