Recently a study was quoted in which it was claimed that in Belfast
more than 40% were R-M222.
I seriously doubt this and would like to see more details.

What study is quoted to that effect? The Busby study perhaps?

>From a post online:

"Now we have a hammer blow from the recent Busby paper.* Ferret in the data
bank in supplement two and you find that there is more M222 in Belfast
than Donegal. At least on the basis of the samples they took. The highest
concentrations have been found in Belfast, North-Eastern Ireland (44%), and
Mayo, Western Ireland (43%). Outside Ireland there are roughly 10% of men
carrying M222 in Northern England (Yorkshire), Western Scotland (Skye) and
North-Eastern Scotland (Moray). "

Paul Conroy posted a review of that study and his analysis doesn't exactly
say that:

It just gives a breakdown for northern Ireland in general citing two
studies; Busby and Myres et al 2011. The Busby paper cites as it's primary
source the Moore et a Trinity college samples.

According to Paul's notes the 44% figure cited above just refers to
northern Ireland and not to Belfast. And 44% seems much higher than the Trinity
estimates of about 21.5% in the NW. Their graph of M222 population in
Ulster declines markedly the further east you go.
