51.   Instead, tests hunt subtle genetic variations called polymorphisms that can determine reactions to medications.

52.   Moderate alcohol consumption has long been known to ward off heart disease, but the latest research shows the influence of this one genetic variation.

53.   Testing women for a common genetic variation may help doctors predict which patients can lower their risk of heart disease by taking estrogen.

54.   The apparent link between heart disease and this common genetic variation was first reported in April by the same researchers.

55.   Understanding such genetic variations is the essence of pharmacogenetics.

56.   Dowsett said it would be a relatively simple scientific exercise to determine genetic variation data in individual Polynesia countries.
