There are two common variants of MTHFR deficiency. In the more significant of the two, the individual is homozygous for the 677T polymorphism. This variant in particular is the most common genetic cause of hyperhomocysteinemia. [9] The resulting enzyme is thermolabile and in homozygotes, enzymatic activity is depressed to 35% of its usual level ...
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 .
C677T or rs1801133 is a genetic variation—a single nucleotide polymorphism (SNP)—in the MTHFR gene. Among Americans the frequency of T-homozygosity ranges from 1% or less among people of sub-Saharan African descent to 20% or more among Italians and Hispanics. [1] It has been related to schizophrenia [2] Alzheimer's disease [3] depression [4 ...

The most common polymorphisms are known as MTHFR C677T and MTR A2756G. [23] [24] The homozigote mutation G;G also called C;C (it is equivalent) occurs in about 10% of the population of european ethnicity (white caucasians). [25] Elevations of homocysteine can also occur in the rare hereditary disease homocystinuria. [citation needed]
