这是人体内的一个SNP位点,它表示,在MTHFR基因中,在第677个核苷酸位点上,由C转变为T突变。 基本简介 基因突变(gene mutation)是由于DNA分子中发生碱基对的增添、缺失或替换,而引起的基因结构的改变,就叫做基因突变。1个基因内部可以遗传的结构的改变。又称为点突变,通常可引起一定的表型变化。广义的突变包括染色体畸...

This article reviews the research advancement in the relationship between MTHFR-677C/T polymorphism and depression in recent years on the basis of MTHFR gene mutation and function, lack of folic acid, elevated plasma homocysteine levels and the MTHFR-C677T polymor-phism. Based on which we hope...
Conclusion There was genetic polymorphism in MTHFR C677T among the chinese children with han nationality. The genetic polymorphism in MTHFR C677T was more common in DS group. The mutation of this gene site may leat to lower activity of the key enzyme which takes part in the folic acid ...

making it a cornerstone of our genetic makeup. A staggering 80% of us carry a mutation in one of the MTHFR gene’s two most critical alleles (C677T or A1298C), which can significantly impair our ability to metabolize folate (folic acid)—the main catalyst for methylation. This reduction...
像您后半句问的MTHFR基因的C677T是完全能够检测到的，只是这个基因的这个位点的突变大多数不代表致病性...
and the DNA from whole blood was extracted. MTHFR C677T, A1298C gene mutation site and the MTRR A66G gene mutation site was detected by real-time PCR. And the gene frequency distributions were analyzed. Results The frequency distributions of CC, CT and TT genotypes of MTHFR C677T loci ...
