I have had severe M.E. for 30 years since aged 20 and am bedbound except can get out to go to toilet. My mother (mostly housebound) and two sisters (mostly bedbound) also have severe M.E. Thankfully our father doesn’t have ME even though we all live together. If we had genetic testing would it show anything treatable about my mother, sisters and me (I am male) which isn’t in my father’s genes? People seem to use results for methylation but I’ve tried methylcobalamin and metafolin without success a few years ago, though started trying them again now, and my sisters have tried lots of B vitamins. Is there anything else that anyone has found treatable from genetic testing? My mother, one sister and I are all deteriorating over the years especially our brains, one of my sisters is stable. We don't understand this because most people don't deteriorate? Are there any privacy options with 23andme e.g. what do the companies do with the results? Many thanks in advance.
