Your genes are the instructions for your body’s development and function. Sometimes changes occur in these instructions. This can cause genetic conditions.

Around half of all Australians will be affected by a condition that is at least partly genetic in origin. These conditions may be present at birth or appear later in life.

About genes and genetics
