A very interesting paper has only just been published (thanks to Ian Logan from Rootsweb): Achilli et al., Mitochondrial DNA Backgrounds Might Modulate Diabetes Complications Rather than T2DM as a Whole, PloS ONE 6(6).http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0021029
Of course the authors are interested in the medical implications, which are of course only statistical (to understand if an haplogroup is more or less linked to some disease), but this study has for us also important genealogical meanings. They have done an FGS of some samples and these are the conclusions we can draw:
1) The samples are from The Marche (Italy).
2) They have done an FGS also of some R0a-s I signalled for a deep test, to understand which is their origin.
3) Exactly this haplotypes I spoke about are the R0a-s with the mutations in HVR1, beyond the two common to this haplogroup (16362 and 16126), 16266 (present in an American of Italian descent from Tuscany and an Italian from The Marche), and the mutations 16230 and 16497, present, beyond the previous paper on Etruscans of the same Achilli, in a relative of mine from Tuscany. These last mutations, even in that paper which tried to demonstrate that Etruscans came from Asia Minor, were found only in Tuscany. Now we know that Tuscany and The Marche have these haplotypes, found now also in other persons.
4) Judging from the mutations found by an FGS, I think I can say that these haplotypes are in Italy from many thousands of years.
