| 服务名称： | 亚甲基四氢叶酸还原酶基因(MTHFR)C677T位突变检测 |
| 规格： | C3491-50UL |
亚甲基四氢叶酸还原酶(MTHFR) 677C→T 基因突变使丙氨酸(A)被缬氨酸(V)取代,导致酶的耐热性和活性减低,血同型半胱氨酸(Hcy) 水平升高,成为心血管病和神经管缺损的独立风险因素。

.0003 MTHFR THERMOLABILE POLYMORPHISM [MTHFR, 677C-T, ALA222VAL]
Frosst et al. (1995) identified a 677C-T mutation in the MTHFR gene, resulting in an ala222-to-val (A222V) substitution. The alteration created a HinfI site that was used to screen 114 unselected French-Canadian chromosomes; the allele frequency of the substitution was 0.38. The mutation in the heterozygous or homozygous state correlated with reduced enzyme activity and increased thermolability in lymphocyte extracts; in vitro expression of the mutagenized cDNA containing the mutation confirmed its effect on thermolability of MTHFR. Individuals homozygous for the mutation had significantly elevated plasma homocysteine levels. Thus, the 677C-T mutation may represent an important genetic risk factor in vascular disease.
