Last week, I was interviewed by Theral Timpson for the Mendelspod podcast episode called “Family Surprises Care of the DNA Test.”
There is a lot of misinformation spreading online about a gene all of us have called MTHFR. (We each have two copies it, actually: one from mom and one from dad.)
Self Magazine published an article this week specifically addressing the MTHFR gene and all the facts we know about it. It was written by Tara C. Smith, a person with a PhD in epidemiology. Epidemiology is the study of how different factors influence the health of people, and those with a PhD are trained to understand the outcome of studies at both the group level (large populations) and at the individual level (YOU!).
I read this article yesterday and feel like it is the BEST ARTICLE to date on MTHFR. It will be accessible to most readers, no matter your level of knowledge about DNA or genetics research.
How do you know if a DNA company you found online is reputable? And whether its results are reliable? These are common questions. And they are difficult to answer.
If you're asking about tests that will give you ancestry or genealogy information, the International Society of Genetic Genealogy is a great place to turn. Their beginner's guide section has a list of articles to get you headed down the right track. I've also written about choosing between the options in this area of DTC testing before and linked to other articles with advice in this blog post.
