NFINITI Factor II-V & MTHFR Assay
- The INFINITI Factor II-V & MTHFR Assay is CE Marked.
- The INFINITI Factor II-V & MTHFR Assay is designed to identify genetic variants of Factor II, Factor V Leiden, and MTHFR genes.
- The INFINITI Factor II-V & MTHFR Assay utilizes the Factor II-Factor V Leiden-MTHFR Intellipac, Factor II-Factor V Leiden-MTHFR Amp Mix and Factor II-Factor V Leiden-MTHFR BioFilmChip Microarray.
- The INFINITI Factor II-V & MTHFR Assay is automated by the INFINITI Analyzer.
- Factor II (Prothrombin): G20210A
- Factor V Leiden: G1691A
- MTHFR: A1298C and C677T
- Simultaneous Multiplexed determination of 4 genetic variants for Factor II (Prothrombin), Factor V Leiden, and MTHFR
- Rapid turnaround time enhances workflow efficiency.
- Load & Go automated on the INFINITI/INFINITI PLUS Analyzer.
- Replicate determinations on a single BioFilmChip Microarray ensures quality results.
Sample Type and Volume:
- Requires 50 ng DNA / reaction
- The Factor II (Prothrombin) variant gene is the second most common genetic defect for inherited thrombosis.
- The Factor V Leiden mutation is the most common variant associated with inherited thrombosis.
- FV mutation has a high prevalence in the general population (4 – 6% of US Population), and accounts for 85-95% of activated protein C resistant cases.
- Enhanced risk of venous thrombosis, with the presence the Factor V Leiden variant, with odds ratios (ORs) of 3 to 8 in heterzygotes and 30 to 140 OR in homozygotes.
- Genetic variations in the MTHFR gene can cause hyperhomocysteinemia, which can lead to a host of ailments
including risk of blood clots, heart attacks, and miscarriages in women
- The increased risk of venous thrombosis in patients who are heterozygous for the prothrombin (G20210A) gene polymorphism is 3-fold.1
- Homozygotes for this polymorphism have been described but are very uncommon.1
- Patients with a previous, or current, thrombotic event that have the prothrombin (G20210A) gene polymorphism are potentially at increased risk for recurrence.1
- Patients with the prothrombin (G20210A) mutation are at increased risk of thrombosis when exposed to other risk factors such as:
- (1) smoking
- (2) pregnancy
- (3) Obesity
- (4) Oral Contraceptives
- (5) Immobility1
- “The risk of thrombosis is substantially increased for patients with multiple genetic risk factors (i.e., the “double hithypothesis”) including the prothrombin (G20210A) gene mutation, Factor V Leiden Leiden mutation, hyperhomocysteinemia, methylenetetrahydrofolate reductase (MTHFR) thermolabile polymorphism, protein C deficiency, protein S deficiency, and antiphospholipid antibody syndrome(s).”1
- Definition and confirmation of the prothrombin (G20210A) gene polymorphism is necessary for genetic counseling of patients for themselves and family members.
- Identifying women who are at risk for multiple stillbirths and spontaneous miscarriages.
- Assessing the risk of cancer patients at risk for venous thrombosis.
- Preventing thrombosis in women who are taking oral contraceptives or hormone therapy.
