Factor V Leiden is a common change in a gene that controls a protein called Factor V. Factor V Leiden gene change (also called mutation) is linked to an increase risk of blood clots.
Factor V Leiden mutation is common ? it occurs in about 1 in every 20 ? 25 people in Australia. No treatment to change genes is currently available.
Most people who have Factor V Leiden mutation do not need any treatment but need to be careful at times when the risk of getting a blood clot may be increased.
Testing is easily done ? a simple blood test is all that is required. Most people think testing is a good idea but you and your family should think carefully about testing for the Factor V Leiden mutation. T
