Traits Reported

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.

Gene Heritage does not report on traits of clinical importance. Traits and genes listed under Digestion & Metabolism and Smell & Taste Sensitivities are health related, but not clinically important.

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.
