The enzyme methylenetetrahydrofolate reductase, encoded by the MTHFR gene, plays a key role in this process. The presence of point changes (polymorphisms) in this gene significantly reduces the activity of the enzyme, blocking the conversion of ordinary folic acid into its active, safe form.<\/p>\n<p data-path-to-node=\"7\">Two polymorphisms are of greatest clinical significance: <b data-path-to-node=\"7\" data-index-in-node=\"52\">MTHFR C677T<\/b> and <b data-path-to-node=\"7\" data-index-in-node=\"67\">MTHFR A1298C<\/b>. In the presence of these genetic variants, the body begins to rapidly accumulate an intermediate metabolic product - the amino acid homocysteine. In high concentrations, homocysteine acts as a toxin: it damages the inner wall of blood vessels (endothelium), triggering the processes of early atherosclerosis, the formation of blood clots and increasing the risk of sudden cardiovascular catastrophes.<\/p>\n<h3 data-path-to-node=\"8\">The main indications for the analysis:<\/h3>\n<ul data-path-to-node=\"9\">\n<li>\n<p data-path-to-node=\"9,0,0\"><b data-path-to-node=\"9,0,0\" data-index-in-node=\"0\">Obstetrics and reproductive medicine:<\/b> preparation for pregnancy (especially if there is a history of habitual miscarriage, stillbirth, placental abruption, or congenital neural tube defects in the fetus).<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"9,1,0\"><b data-path-to-node=\"9,1,0\" data-index-in-node=\"0\">Cardiology and vascular surgery:<\/b> assessment of the tendency to thrombosis, early myocardial infarctions, strokes and <a title=\"Gut microbiome and chronic diseases: scientific and clinical analysis\" href=\"https:\/\/medilab.km.ua\/en\/gut-microbiome-and-chronic-diseases-scientific-and-clinical-analysis\/\" data-wpil-monitor-id=\"81\">chronic ischemic disease<\/a> hearts.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"9,2,0\"><b data-path-to-node=\"9,2,0\" data-index-in-node=\"0\">Neurology:<\/b> searching for the causes of chronic migraines, depressive states, and cognitive disorders, since folates directly affect the synthesis of the neurotransmitters serotonin and dopamine.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"9,3,0\"><b data-path-to-node=\"9,3,0\" data-index-in-node=\"0\">Therapy control:<\/b> selection of the correct form of vitamins (replacing synthetic folic acid with active methylfolate) and monitoring homocysteine levels.<\/p>\n<\/li>\n<\/ul>\n<p data-path-to-node=\"10\">The Real-time PCR method allows for the most accurate determination of the patient&#039;s genotype (normal, heterozygous or mutant homozygous).
