[Structural analysis of the correlations of genetic markers with physiological indices].

The structure of phenotypic and genetic correlations between ABO blood groups, MN, Rh(D), haptoglobins and concentration indications of the total cholesterol, of sugar curve, the levels of systolic and diastolic arterial pressure was studied in twins by the method for cluster analysis (121 monozygotic twin pairs, 120 dizygotic like sex twin pairs and 107 pairs of unlike sex twins). No correlation between the systems analysed and their indications on the phenotypic level was observed. By analysis of genetic correlations, the existence of correlations between the Rh system and arterial pressure, and the total cholesterol concentration, as well as between the ABO system and sugar concentration indexes, was established. Possible genetic causes for correlations obtained are being discussed.
