It pays to gave a son that is an MD w a degree in medical genetics

For example:

For the MTHFR gene, I went to this webpage, https://www.geneticlifehacks.com/mthfr/ to find the SNP rs1801133.

I then went to 23 and Me Raw Data Search, https://you.23andme.com/tools/data/ and pasted SNP rs1801133.

Per Genetic LifeHacks: 

G/G: typical *
A/G: one copy of MTHFR C677T allele, enzyme function decreased by 40%
A/A: two copies of MTHFR C677T, enzyme function decreased by 70 – 80%

I looked up your SNP and it is A / G  

So it might be worthwhile to read about it at the link above.  

Hope this wasn't too complicated,

Luke

This is a complicated subject.
