|
Gene |
HFE |
Chromosomal Location |
6p22.2 |
Allelic Variant 1 |
613609.0001; HEMOCHROMATOSIS |
Identified Mutation |
CYS282TYR; A missense mutation caused by a G-to-A transition at nucleotide position 845 results in a cysteine to tyrosine transition at codon position 282 [cys282tyr (C282Y)] in the HFE gene. |

Gene |
MTHFR |
Chromosomal Location |
1p36.3 |
Allelic Variant 1 |
607093.0003; MTHFR THERMOLABILE POLYMORPHISM |
Identified Mutation |
677C>T; Frosst et al. [Nature Genet. 10: 111-113 (1995)] identified a C-to-T substitution at nucleotide 677 that converted an alanine to a valine residue. 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. |
