Introduction to Genomics

Genomic medicine is a powerful tool in improving healthcare for patients and is already embedded in many areas of healthcare provision.

The words ‘genome’ or ‘genomic’ refer to a person’s complete set of genetic information. This includes all parts of the DNA – the instructions for building and operating a person’s body.

Genomic medicine uses the information in our DNA to inform and personalise medicine, which can help improve diagnosis, treatment options and prevention for a wide range of conditions.

 

Why is Genomics important in healthcare practice?

By studying an individual’s genome, healthcare professionals can identify differences that may contribute to a disease, allowing them to provide personalised treatment and interventions that are most likely to be effective.

A person’s genetic makeup also impacts the effectiveness of certain medicines and can even lead to unwanted side effects. We call this ‘pharmacogenomics’.

In some situations, early diagnosis using genomic testing can prevent a disease progressing and becoming harmful. For example, in some cancer cases, it can help clarify what screening or active management is needed.
