markmc20001, interesting question about becoming "genetically predisposed" through a retrovirus. Anyone???
I'm also curious if childbearing affects the odds of women contracting ME. For example are the ME rates of women who have not had children comparable to ME rates in men or are they significantly lower than ME rates in women who have had children?
I have to read where I get stuff better. I just realized this site is a white suppremisist site. Sorry, if you already read this. However, they got the summary from government sites. Sorry, it definately was not intentional. I am also Native American and would definately not frequent such a site.
20- 25% of Europeans have the HIV immunity
--------------------------------------------------------------------------------

About 20% of Caucasians have one copy of the gene, about 10% have two copies. Among Caucasian Europeans the gene is more common in Northern Europeans. The gene is virtually absent in Africans, Native Americans and Asians.
It is hypothesized that a devastating epidemic swept through Europe may
thousands of years ago that, like HIV, used a normal CKR-5 protein. Those survivors with a mutant gene survived and reproduced. Natural selection favors the survival and reproduction of the fittest and the gene consequently became more abundant in these populations over time.

Recently, it was shown that a 32-bp deletion in the CKR5 macrophage chemokine receptor gene produced resistance to HIV infection. Frequencies of the CKR5 mutant allele in Russians, Tatars, Uzbeks, Kazakhs, Azerbaijanis, Uigurts, Tuvinians, and Georgians estimated by means of the PCR technique were equal to 0.13, 0.12, 0.85, 0.06, 0.05, 0.04, 0.03, and 0.00, respectively. While the theoretically expected frequency of deletion homozygotes in Russians and Tatars was 1.7%, none of such homozygotes were detected among the 90 persons examined. The data suggested that about 25% of the population in northwestern Russia is highly resistant to HIV infection.
I was reading an article the other day (which now I can't find) that stated people with Native American Ancestors are more likely to get Fibromyalgia and CFS. Weird. I have objibway anscestory on my dad's side of the family (my grandmother).
