Hello David

I think you will find this paper of interest as it tries to explain why mutations about '150'
might affect longevity.
A Combination of three common inherited mitochondrial DNA polymorphisms
promotes longevity in Finnish and Japanese subjects.
Niemi, et al. University of Oulu, Finland
European Journal of Human Genetics 13, 166-170 (2005).
OK. perhaps it is a bit of research that was published because the worker had done it, .... .

But what I really find poor is 'the matching of the subjects' or rather 'non-matching' - I think
all that was done was to look at the subjects ages and no account of the 'disease' or 'health' profile.
was taken at all.

So is there a link between longevity & Haplogroup J - personally I doubt it.


Both my mother in law (lived to be 104) and my greatgrandfather's sister (lived to be 100) were mtDNA haplogroup J. I
believe that there are some studies linking J to longevity. I did not know about HVR2. I guess it all boils down to
the efficiency of oxidative phosphoylation (Krebs Cycle) and how well the cells are then able to carry our their
metabolic functions. I would like to see some evidence as to the result of this supposed efficiency. Perhaps it allows
for the better emulsification (breaking up) of lipofuscin (age pigments in the cell).
