International ME/CFS and FM Awareness Day Is On May 12, 2018
Thomas Hennessy, Jr., selected May 12th to be our international awareness day back in 1992. He knew that May 12th had also been the birthday of Florence Nightingale. She was the English army nurse who helped to found the Red Cross as well as the first school of nursing in the world.

    My results for this gene are TT, however, this snpedia page lists results as either AA or AG or GG. I've had this before, i.e., my results are not noted on the snpedia page... Can someone enlighten me re the alternative results (like TT) that are not noted on the page? thanks.

    Yeah, it does get confusing at times. It has to do with the double-stranded nature of DNA. A goes with T and G goes with C so some places refer to one side and some refer to the other.

    Here's a quote from the 23andMe site:

    23andMe reports results on the forward strand, but some research and other sources use the reverse strand. If your results don't match up, then A=T and C=G. So your TT result would translate to AA on that site.
