Not very clear which is the motivation behind or the peculiar interest of this paper but it should add to the data resources anyhow:
Matthew C. Dullik et al., Y-Chromosome Variation in Altaian Kazakhs Reveals a Common Paternal Gene Pool for Kazakhs and the Influence of Mongolian Expansions. PLoS ONE 2011. Open access.
The data adds to and is compared with previous research (several papers) on Kazakhs from Eastern Kazakhstan. Central and Western Kazakhstan remain pretty much unexplored.
There are some difference in the respective Y-DNA pools but they seem to originate in differential founder effects and not specially in admixture with Altays. Notably:
- Altay Kazakhs are higher in C(xC3c) (24%) and lower in C3c (39%) than other Kazakhs.
- They are also higher in O3 (26%)
- They are also higher in G and J (9%) altogether
SW Altayan Kazakhs may be admixed patrilinearly with native Altayans, while SE Altayan Kazakhs do not show such affinity. This difference may be caused by sampling in a Christian Khazak community living side by side with Altayans and Russians.

It is interesting that while the genesis of the Kazakh nation lays historically in separation from Uzbeks, these two Turkic nations do not share almost any lineage.
The poor sampling of Kazahstan and even Kazakhs in China is admitted by the authors as a problem to properly understanding Kazakh genesis. As mentioned before most samples come from Eastern and SE Kazakhstan however most of the country remains unsampled.
