My understanding is that the OTC DNA tests were severely restricted by the FDA a few years ago. The prohibition was to not provide health explanations of the SNPs reported.
That has been changed recently, but I don't know in what regard the change liberalizes the reporting.
Here is a good PDF however...explaining the MTHFR polymorphisms in detail: It also explains the testing etc.

If a person suspects a DNA error but doesn't want to go thru the testing and personal research of the reported SNPs, they can just take the methylfolate and methylcobalamin... Neither is RX and not dangerous to self monitor.
