For me, at least, it isn't a questioning of disbelieving the DNA but rather understanding the evolution of the science. Nor do I see this position as necessarily one that casts me as an Anna Anderson "supporter;" rather, I try to keep an open mind and explore the possibilities and the unanswered questions.
One needn’t believe in conspiracies or ascribe incompetence to those who conducted the testing to have doubts about their continued validity. Two distinct methods of DNA testing were used to show support for the hypotheses that Anastasia Manahan or Anna Anderson 1) Could not have been a child of Nicholas and Alexandra; 2) Did not match the mtDNA Hessian profile derived by Gill and used to match four of the female Ekaterinburg remains to the profile derived from HRH The Duke of Edinburgh; and 3) Matched the mtDNA profile of Karl Maucher, lending support to the hypothesis that she was Schanzkowska.
Both nuclear and mitochondrial (mtDNA) testing was done. Nuclear testing is preferred as it renders better results and is considered more accurate, while mtDNA is less discriminating. Nuclear DNA tests showed that AA could not possibly have been a daughter of N and A, yet changes in the science make the 1994 verdict obsolete. Gill used a 6-point Short Tandem Repeat (STR) analysis of the nuclear DNA to arrive at these results. Within four years of these tests, 10 point STR testing was being done, and when results of 10 point STR testing were compared with 6 point STR tests, the 6 point analysis was shown conclusively to give both false positive and negative results-in other words, conclusions based on 6 point STR tests were proved faulty. In 1999, the testing had gone from the 6 point STR tests of 1993-94 and the 10 point STR tests of 1998 to 12 point STR tests, the accuracy of which further undermined 6 point STR test results. Gill admitted this in a statement released in 2000, adding that FSS had changed from the old 6 point STR method to the 10 point STR method in 1999. In 2000, the STR tests were up to a 14 point system; in 2001, it was 16 points, and by 2002, the industry standard worldwide in STR testing was 20 point STR tests. Scientific studies have repeatedly shown that 6 point STR tests are unreliable and result in false matches and exclusions. The 6 point STR nuclear DNA tests that showed Anastasia Manahan could not have been a daughter of N and A, therefore, are now meaningless.
The mtDNA match to the Maucher profile is also now known to be less reliable than everyone believed. In 1994, mtDNA matches were believed to prove identity, and to be unique to related individuals. Last year, an extensive UK study showed that out of a random 100 persons, four completely unrelated subjects shared exactly the same mtDNA profiles; extrapolate that here, on a board with 400 members: of the 400 of us posting here, 40 of us-unrelated to each other-would have identical mtDNA profiles, thus "proving" that we're related. The odds of a random mtDNA match between the Manahan sample and the Maucher profile are indeed considerable given the size of the world’s population and the numbers involved. I suspect, based on the continuing evolution of the science, that future studies will show mtDNA profiles to be even common than this.
My reservations about regarding the 1994 DNA tests as absolutely conclusive in the matter of Anastasia Manahan, therefore, rest on the advances of science. Two of the three planks in the DNA case against her have now been shown to be either unreliable or less than compelling in a mere ten years. Her exclusion from the Hessian mtDNA profile remains, and while the methods used to obtain the exclusion remain in practice, given the above changes I hesitate to presume that they, too, won’t be challenged as the science evolves; already in the last 2 years there have been two substantial challenges to the DNA testing done on the Ekaterinburg remains, and I suppose there will be more in the future that may or may not be valid. This makes it theoretically possible-given the facts above about the first two DNA planks in the case-that ultimately in another generation none of the DNA identifications/exclusions in the Anderson case will matter-and the case will fall back to where it always rested before the DNA-to examination of physical traits, memories, recognitions, etc.
It seems to me, whether one wishes to believe in Anna Anderson or not (and I don't wish either way, incidentally), it’s best to keep an open mind and at least examine the facts as known now in the DNA case against Anastasia Manahan-as three separate issues-rather than repeatedly refer to ten year old tests that, taken as a whole, have lost two-thirds of their validity.
