WebThis test detects pathogenic alterations in the F5 gene to delineate the underlying molecular defect in a patient with a laboratory diagnosis of coagulation factor V deficiency. This test may also detect rare alterations in F5 that cause activated protein C resistance, resulting in thrombophilia. The gene target for this test is: Factor V Leiden (rs6025 or F5 p.R506Q ) is a variant (mutated form) of human factor V (one of several substances that helps blood clot), which causes an increase in blood clotting (hypercoagulability). Due to this mutation, protein C, an anticoagulant protein that normally inhibits the pro-clotting activity of factor V, is not able to bind normally to factor V, leading to a hypercoagulable state, i.e., an increased tendency for the patient to form abnormal and potentia… register lateral flow test results onlineWebIn particular, the well-known Leiden mutation G1691A (Factor V Leiden, rs6025) causes APC resistance which is associated with an increased risk of VTE and pregnancy complications, such as RPL [4,9].
