摘要
A unique variant of mitochondrial DNA polymorphism was detected in an Olkhon Buryat living in the Irkutsk region. The main characteristic of this variant is the presence of a long insertion ANATTGAGA in the hypervariable segment I of the control region of mitochondrial DNA. Taking into account multiple nucleotide substitutions and 2 insertions in the mitochondrial genome fragment, we hypothesize that intense rearrangements in the mitochondrial DNA can be caused by ecological factors, e. g. high background radiation of a technogenic origin.
