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. |

| Remarks |
Mild symptoms; donor subject is a compound heterozygote for mutations in the CFTR gene: allele one carries a deletion of codon 508 (CTT) in exon 10 which leads to deletion of phenylalanine-508 [PHE508DEL] and allele two carries a G-to-A transition at nucleotide 482 (482G>A) in exon 4, resulting in a change of arginine to histidine [ARG117HIS (R117H)]; analysis of a DNA variant in a noncoding region of the CFTR gene (polypyrimidine tract in intron 8) showed this donor has alleles 5T/9T; donor subject is homozygous for a C>G transversion at nucleotide 187 in exon 2 of the HFE (HLA-H) gene [187C>G] resulting in a substitution of aspartic acid for histidine at codon 63 [His63Asp (H63D)]; donor subject is heterozygous for a C>T mutation at nucleotide 677 in exon 4 of the methylenetetrahydrofolate reductase (MTHFR) gene [677C>T] that results in a substitution of a valine for an alanine at codon 222 [Ala222Val (A222V)] |
