General Information

 Methylenetetrahydrofolate reductase (MTHFR) gene

It is involved in the conversion of folate (vitamin B9) into its active form. The most commonly studied variants of this gene are C677T and A1298C, which may affect the activity of the enzyme.

C677T variant:

  • Associated with decreased activity of the MTHFR enzyme;
  • Especially in the TT homozygous state, homocysteine ​​levels may be elevated, especially in folate deficiency.

A1298C variant

  • It may also reduce enzyme activity, although its effect on homocysteine ​​levels is usually less pronounced.

It is important to note that The presence of an MTHFR variant does not in itself mean disease.The outcome should be evaluated taking into account homocysteine, folate, B12 levels, and the patient's clinical condition.

Study material: Venous blood

When should we take the test?

  • When homocysteine ​​levels increase
  • When assessing folate or vitamin B12 deficiency;
  • In certain cases of recurrent thrombosis or pregnancy complications (at the doctor's discretion);
  • In the presence of a family history, if there is suspicion of metabolic disorders
  • To detect genetic thrombophilia

Possible interpretation of the results

C677T and A1298C are the most common polymorphisms of this gene. Their presence does not in itself indicate disease and the results should be interpreted in conjunction with clinical data and, if necessary, homocysteine ​​and folate levels.

MTHFR polymorphisms are very common. and is found in a significant portion of the population

The detection of the C677T and A1298C polymorphisms of the MTHFR gene is a common genetic feature and in most cases does not require treatment on its own. The results should be evaluated taking into account the patient's clinical condition and additional laboratory indicators.

 

Reference values

MTHFR extension The gene synthesizes the enzyme methylene-tetrahydro-folate-reductase, which participates in the process of protein formation from amino acids. Its participation in the metabolism of folic acid is important, because the mirate form of folate is involved in the conversion of homocysteine ​​to methionine. Methionine is an essential component for the formation of proteins and other compounds.

MTHFR extension Up to 40 gene mutations have been found in people with homocystinuria. Homocystinuria is a condition when the conversion process of homocysteine ​​to methionine is disturbed. Such people often have: coagulation disorders, skeletal and nervous system development anomalies, damage to the organ of vision, retardation of mental development and others.

MTHFR extension The 2 most frequent gene mutations C677T and A1298C lead to a decrease in enzyme activity and are associated with the development of such pathologies as: homocystinuria, coagulation disorders, anencephaly, spina bifida and others.
