Goga,
I appreciate your answers, but please acknowledge that you are in no position to question my Circassian heritage. The same way I cannot say anything about how Iranian you are based on your genetic results. It would be ridiculous.
I assure you that I am Circassian. I live in Turkey, but all my ancestors are known to be Circassian. Turkey is the country where the majority of my people live due to the massive displacement of Circassians from historical Circassia in Russia today. You are asking me why I score different than those in Russia. I have answered to this question somewhere else. I'm reposting it.
I think this is because the only Circassian data used in such studies stem from people who still live in Russia where not all Circassian sub-branches or tribes exist today.
However, the majority of Circassians live in diaspora. Most of the extended families live in Turkey, Israel, and Jordan, amongst others. I am from one of them, my family lives in Turkey since the second half of the 19th century. I belong to the sub-branch of Kebertei, but my paternal family is currently non-existant in Russia. All my ancestors are known to be Circassian (from Kebertei aka Cabardians). I still live in Turkey. It is true that my Caucasus HG score is lower, but I believe it is a main component for South Caucasians and some North Caucasians, rather than Northwest Caucasians like Circassians. Here's an analogy for you to better understand this. It's about the Abhaz people who are also a West Caucasian. Well, I have seen once a study which includes the Abhaz both from Abhazia and Turkey (the latter having the largest Abhaz population in the world, too). The thing is they scored much different than each other as Abhaz in Abhazia had lower North Euro admixture just like Georgians, whereas Abhaz in Turkey scored much higher North Euro, being closer to Circassians. Perhaps, those in Abhazia have recent ancestry from Georgians, just like Circassians in Russia can have recent ancestry from other North Caucasians who might have lowered the Circassian basal WHG. You cannot simply assume that Circassians in Russia are more representative. In Turkey, there are Circassians who have recent Turkish admixture, too. Yet in general, we are an isolated population in Turkey. That's why most of us have preserved our Circassian features which are fair, but you should already know this if you really know about my people.
Best
