Data for the distribution of alleles controlling two blood group systems and secretor status, for hemoglobin types, five serum protein groups and 15 red cell enzyme systems has been obtained. Eleven of the systems showed polymorphic variation and these systems have been used to calculate genetic distances using Morton's Kinship measure. No systematic relationship between genetic distance and geographic location of linguistic affiliation is apparent. There is, however, an apparent cline of decreasing frequency of PGDc from east to west and also significant differences in the frequency of G6PD deficiency corresponding to variation in the ecology of the region. Genetic distance comparisons with other selected populations reveal that the Turkic and Turkoman speaking peoples in the Caspian area cluster with the Kurds, Greeks and Iranis. The Persian speakers are genetically remote from these populations; they are, however, close to the Parsis who migrated from Iran to India at the end of the Seventh Century A.D. Several unusual genetic variants were detected, including a novel MDH phenotype, a superoxide dismutase phenotype identical with the Scandinavian type, and rare forms of LDH, PGM locus 2, ceruloplasmin, diaphorase, peptidases and PHI.

Ceruloplasmin possesses antioxidant activity in vitro, but such a property has not been substantiated in vivo so far. However, it has been suggested that the lack of factors protective against oxidative haemolysis might have a role in neonatal hyperbilirubinaemia. Ceruloplasmin and alphafetoprotein concentrations were measured in cord blood in 78 unselected full-term singleton newborn infants without G6PD deficiency and haemolytic disease of the newborn; in the same infants, the carboxyhaemoglobin level was assessed on the fourth day of life and taken as an index of bilirubin production. The relationship between these variables and maximum bilirubin level in the first 4 days was studied by multiple regression analysis. High carboxyhaemoglobin levels and low ceruloplasmin concentrations, but not alphafetoprotein resulted, associated with hyperbilirubinaemia (P < 0.001). No relationship was found between carboxyhaemoglobin and ceruloplasmin levels. These results exclude an important role for ceruloplasmin in protecting against possible oxidative haemolysis in full-term newborn infants. Ceruloplasmin levels in cord blood are most probably related to hepatic metabolism and are better predictors of hyperbilirubinaemia than alphafetoprotein concentrations.
