Variant Analysis is a method used to identify and evaluate differences in genetic sequences. This process helps researchers understand how variations in DNA can affect traits, diseases, and responses to treatments. By comparing genetic variants, scientists can pinpoint specific changes that may contribute to health conditions or influence drug effectiveness. In the context of genomics, Variant Analysis plays a crucial role in personalized medicine. It allows healthcare providers to tailor treatments based on an individual's unique genetic makeup. This approach enhances the potential for successful outcomes by considering how specific genetic variants may impact a patient's response to therapy.
