Cardiovascular Genetics Panel

This panel examines a range of inherited genetic variations that can influence your risk of blood clots and cardiovascular disease. Unlike blood tests that measure your current state, a genetic panel looks at variations you were born with, offering insight into your underlying, lifelong predisposition. This can be particularly useful for understanding personal or family risk, especially where there is a history of clots or heart and circulatory disease.

Inherited clotting risk (thrombophilia)

These genetic variations can affect how your blood clots, and some are linked to an increased tendency to form clots:

• Factor II (G20210A) and Factor V (G1691A, HR2): well-known variants associated with an increased risk of abnormal clotting
• MTHFR (C677T, A1298C): variants that can affect how the body processes homocysteine, a substance linked to cardiovascular risk
• Factor XIII (V34L), PAI-1, and Fibrinogen-beta: further variants involved in the clotting and clot-breakdown process

Platelet function

• GPIa and GPIIIa: variations affecting platelets, the cells involved in clot formation, which can influence clotting tendency

Cardiovascular risk

• ApoB and ApoE: variants involved in how the body handles cholesterol and fats, relevant to heart disease risk
• ACE: a variant linked to blood pressure regulation and cardiovascular risk

An important note on interpretation

A genetic variant indicates a predisposition, not a certainty. Carrying one or more of these variants does not mean you will develop a clot or heart disease, and not carrying them does not remove all risk, since lifestyle and other factors play a major role. Results are best interpreted alongside your personal and family history, and any significant findings should be discussed with your GP or a specialist, who may recommend genetic counselling.

Why it matters

Understanding your inherited risk can help you and your doctor make informed decisions about prevention, monitoring, and lifestyle. It can be especially valuable if you have a personal or family history of blood clots or cardiovascular disease, or are planning for situations that carry a higher clotting risk.
