| Summary | Effects due to MTHFR polymorphisms affecting homocysteine? |
| Criteria | Gs193/criteria |
This has been self reported by 3 individuals with no obvious ill effects.
You have rs1801133(T;T) and rs1801131(C;C), variations in MTHFR which are linked to variations in homocysteine levels. This appears to have numerous consequences. See gs192 for similar, but more common genotypes. In [PMID 15834246] it is speculated that this compound homozygous mutation may not be compatible with life. It seems you prove otherwise.
