Hi Marie33, I paid myself to 23andme (look it up online), it was not too expensive. My new neuro didn't seem too interested, but he will test for one specific gene which seems to be very relevant in neurology, SMN1, I think to confirm my diagnosis and to exclude something.

I was stupid enough to order my test from 23andme AMERICAN branch, with FDA restrictions in place, without checking if they operate in the UK also. They do, with no FDA. And I'm actually in Europe. I think my brain was fogged by everything related to my illness.

mrsD, how much methylfolate would you take for every, say, 1000 mg of methylcobalamin? Would you take it with food? Got it today, but not sure what dosage makes sense.

800mcg a day of the methylfolate to start. There are no food restrictions I know of for it.

The methylB12 requires empty stomach and no food after for about an hour.

And this explains your gene in more detail:

They want to exclude SMA, so. ALS is fairly out of question in my case. I have pills of 1000 µg folate, so I will take one daily.
