The title makes it seem like only the inuit who live in the arctic have these genes. But I doubt that's the case.
In Alaska, besides the Native American tribes ("Indians") that also live in some of the same areas, there are Inupiat, Yupik, and Aleut. The Inupiat are fairly closely related in culture and language to the Canadian Inuit, but the Yupik and Aleut are considerably further apart in terms of language. Calling a Yupik an "Inuit" is sort of like calling an Italian "French" just because they both speak a Romance language. They tend to not like that very much. :-)
A twist on this is that even though Native American sounds more correct (doesn't imply being from India, is longer and bureaucratic), they'd actually rather be called Indians. It helps to claim it's short for Indigenous.
