Methylenetetrahydrofolate reductase (MTHFR) plays an important role in the metabolism of Hcy. The rs1801133 polymorphism of the MTHFR gene is a C to T transition at nucleotide position 677 (C667T) in exon 4

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.
