Haptoglobin (HP), transferrin (TF), group-specific component (GC) and alpha-1-antitrypsin (PI) polymorphisms have been studied in Sardinia and the following gene frequencies have been found: HP*1 = 0.389, TF*C1 = 0.754, TF*C2 = 0.213, TF*C3 = 0.032, GC*1F = 0.193, GC*1S = 0.546, GC*2 = 0.260, PI*M1 = 0.607, PI*M2 = 0.221, PI*M3 = 0.126, PI*S = 0.040 and PI*Z = 0.006. These findings confirm the genetic uniqueness of Sardinians compared to the other Italian populations.

Vitamin D-binding protein (DBP) concentrations were determined in the sera of 90 cystic fibrosis homozygotes, 57 obligate heterozygotes, and 46 normal controls. Very significantly lower mean concentrations were found in the sera of CF homozygotes compared with both heterozygotes and controls (P less than 0.01, Wilcoxon Rank Sums Test). Subdivision of the samples by Gc phenotype showed that this relationship held true both in the Gc1 and Gc2-1 phenotypes. The small sample size of the Gc2 genotype makes the significance levels of limited usefulness, but the pattern of variation of DBP levels among CF homozygotes, heterozygotes, and controls was consistent with that observed for the Gc1 and Gc2-1 classes. Haptoglobin levels showed high coefficients of variation when compared among CF homozygotes, obligate heterozygotes, and controls, presumably because of nonspecific elevation in the acute-phase response. Alpha 2-macroglobulin levels were, if anything, slightly elevated in CF homozygotes compared with controls, while albumin levels showed no significant mean differences between these groups. Since the DBP concentration does not vary with age nor with levels of vitamin D and its metabolites, we interpret our results to mean that DBP levels are specifically decreased in cystic fibrosis, perhaps as the result of impaired glycosylation of the protein.

A group of 1916 Russian men donors was studied for 15 electrophoretic blood protein systems, coded by 22 protein loci: Transferrin (Tf), Haptoglobin (Hp)--2 loci, Group-specific component (Gc), Hemoglobin (Hb)--2 loci, Lactatdehydrogenase (LDH)--2 loci, Malatdehydrogenase (MDH), Erythrocyte esterase (Est)--4 loci, Albumen (Alb), 6-phosphogluconatdehydrogenase (6 PGD), Phosphoglucomutase (PGM)--2 loci, Esterase D (Est D), Adenosindesaminase (ADA), Acid Erythrocyte phosphatase (AcP), Glutamic transaminase (GPT) and Glioxalase-I (GLO-I). Ten loci were defined as polymorphic, the level of heterozygosity for cumulative loci was 0,1435 +/- 0,003. Moscow population was compared to major human races for the set of genetic characters--heterozygosity, correlation coefficient of single locus heterozygosity, a genetic distance. It has been shown that the extent of relation of ethnic groups to Moscow population decreases as follows: Caucasoids, Mongoloids, Negroids.
