MTHFR is the rate-limiting enzyme in the methyl cycle, which includes the conversion of homocysteine into methionine. Defects in variants of MTHFR can therefore lead to hyperhomocysteinemia. [9] There are two common variants of MTHFR deficiency. In the more significant of the two, the individual is homozygous for the 677T polymorphism.
Methylenetetrahydrofolate reductase (MTHFR) is the rate-limiting enzyme in the methyl cycle, and it is encoded by the MTHFR gene. [5] Methylenetetrahydrofolate reductase catalyzes the conversion of 5,10-methylenetetrahydrofolate to 5-methyltetrahydrofolate , a cosubstrate for homocysteine remethylation to methionine .

Assess the patient to determine if other signs and symptoms are present: flushed face, hot, dry skin, low output, concentrated urine, anorexia, constipation, diarrhea, or vomiting. Older children may complain of sore throat, headaches, aching, and nausea, as well as, other symptoms. [17] Pulse should be checked at distal and proximal sites.
It is used for alert (conscious) people, but often much of this information can also be obtained from the family or friend of an unresponsive person. In the case of severe trauma, this portion of the assessment is less important. A derivative of SAMPLE history is AMPLE history which places a greater emphasis on a person's medical history. [2]

The un-methylated form, folic acid (vitamin B 9), is a synthetic form of folate, and must undergo enzymatic reduction by dihydrofolate reductase to become biologically active. [1] It is synthesized in the absorptive cells of the small intestine from polyglutamylated dietary folate. It is a methylated derivative of tetrahydrofolate.
