Most traits result from a combination of both genes and environmental factors. Even in the cases of traits determined by genes, raw DNA data still can't perfectly predict a trait. Raw DNA data has occasional errors.
All traits in Gene Heritage reports have a predictability score of Highly, Fairly, or Barely Predictable. Look at this score to keep in mind how much genes can predict a reported trait.
To find out what traits or risks you may have that might benefit from clinical treatment, talk to your health care provider or a genetic counselor. The National Society of Genetic Counselors has a directory of genetic counselors.
