Yasko says to treat the SNPs in this order SHMT/ACAT, CBS, MTHFR, MTR/MTRR, BHMT, MAO A, SUOX, NOS, VDR.
You have ACAT, so start there, then CBS, then MTHFR.
Go to the Heartfixer page for more specific information. What I did is make up a Word document with my SNP chart at the top, and then the specific SNP description from Heartfixer in the order they need to be treated. Then I had a custom treatment plan in the order I need to have it.

Once you get into the meat of it (MTHFR/MTR, methylfolate and B12), you'll have to be careful about ODing on too many methyl groups, because of the COMT mutation. So no Freddd type protocol for you. Keep some sustained release niacin on hand in case you OD. It will dampen down the reaction quickly.
In general, research everything carefully before you start popping pills. Starting with very low doses (a fraction of a pill) and gradually work up to full doses as tolerated. Start one new supplement at a time. If you getting a negative reaction, stop the supplement, let it clear out, then restart at a much lower dose. This is known as "start low and go slow". This practice will help you avoid adverse effects. Of course, you should run this past your physician before starting.
