  • Research. Genetic conditions do not seem to be triggered by outside factors, such as viruses or bacteria. instead, the condition runs in families, indicating a strong genetic influence. For instance, sickle cell anemia is a genetic condition that has a predictable pattern in families. The common cold, however, does not seem to run in "families" and instead runs through an entire population without regard to genetics.

    There are, of course, some conditions that cause a specific response to genetics. For instance, if a virus triggers a gene to produce to the wrong protein, then it would be considered a genetic precurser.

  • First they look for common traits in a condition if they need more answers beyond that they do genetic testing on blood.
