If I have a positive result, does that mean I will get the condition?

Not always. A positive result means you have a genetic change that increases your risk, but it doesn’t mean you will definitely develop the condition. These genetic changes are called pathogenic or likely pathogenic variants. 

Other things, like your lifestyle, environment, and even chance, also play a role. Some people with the same genetic change never get the condition, while others do. This is because genes can act differently in different people.
