gb HEMO MTHFR (C677T)
allelic discrimination, real-time PCR
The kit is intended for detection of mutation C677T in MTHFR gene in human genomic DNA. Detection is based on real-time polymerase chain reaction (qPCR) using fluorescently labelled probes (allelic discrimination).
Methylenetetrahydrofolate reductase (MTHFR) is the main regulatory enzyme involved in homocysteine and folic acid (folates) metabolisms. This mutation leads to enzyme activity reduction, increase of homocysteine level in blood and methionine deficiency. However, lower catalytic activity of MTHFR enzyme means higher utilisation of 5, 10-methylenetetrahydrofolate in DNA synthesis or repair.
The risk of venous thrombosis increases in combination with other risk factors (e.g. mutation in MTHFR gene – A1298C, mutation G20210A in factor II, Leiden mutation, long-time immobility, incorrect regimen, hormonal contraception) and grows with the number of mutated alleles in genotype.
