Don't know about the specific test but my daughter was tested and she has a duplicated gene. The doctor couldn't tell us much but it helps their genetic research. I read online that people with this particular gene duplication tend to be thin but my daughter isn't too skinny yet. What's weird is that a doctor told us our kid would be less likely to have genetic problems because we come from different parts of the globe and are different races.

She doesn't have any gut issues that posters bring up or problems with gluten. Diets don't change genes.
