[Distribution of serum protein antigens of the Gm and Inv systems in the Armenian population]. / Osobennosti raspredeleniia antigenov syvorotochnykh belkov sistem Gm i Inv v armianskoi populiatsii.

Serum protein distribution of the Gm system was studied considering 6 enzymes in 1006 and of the Inv system in 568 virtually healthy persons of Armenian nationality. The serum factors Gma, Gmb, Gmx and Inv(I) were defined by hemagglutination inhibition with the help of anti-Gma, anti-Gmb, anti-Gmx and anti-Inv(I) sera method. The reaction included also the anti-D sera which contain the corresponding antigens of the systems mentioned dispensed by the "Biotest--Serum" firm. Establishment of genetic distances and comparative analysis of the authors' results as well as the literature data about the distribution frequency of the serum factors Gma, Gmb, Gmx and Inv(I) in Armenians and in the main ethnic groups of the world made is possible to state that similarity exists between Armenian and European populations.
