Exploration of the genetic variations in the populations leaving in extreme climates will lead to better understanding of molecular-genetics mechanisms of adaptation. In the current study we investigated the genome-wide data of Khahty, Mansi, and Nenets people for signatures of selection using the population branch statistic test and revealed strong signals located in a cluster of alcohol dehydrogenase 1 genes. We hypothesize that it can be due to the limited diversity of food intake the indigenous people of the Northern Ural and Siberian experience.
