Frequency of occurrence of TFC and GC subtypes and determining genes was evaluated in 90 and 68 nonrelated psoriatic patients, respectively. The obtained distributions of frequencies were compared with those recorded in healthy population. No statistically significant differences were observed.
In a sample of the Polish population of 261 unrelated adults, six types of phosphoglycolate phosphatase (PGP) were encountered. From the distribution of phenotypes obtained, the following frequency of genes was calculated: PGP1 = 0.8429, PGP2 = 0.1399 and PGP3 = 0.0172. PGP types were also determined in 12 families with 30 children and in 55 mother-child pairs. In the group of children the observed distribution of types was consistent with assumed types. The usefulness of this system in disputed paternity cases is as high as 13.52%.
Gc subtypes were analyzed by isoelectric focusing on thin-layer polyacrylamide gel. In the sample of the Polish population including 278 persons, six Gc phenotypes were encountered: 1S, 1F-1S, 1F, 2-1S, 2-1F, 2 with the following frequencies: 0.342, 0.151, 0.014, 0.360, 0.072 and 0.061. Frequency of Gc1S was 0.597, Gc1F - 0.126 and Gc2 - 0.277. It was shown that a group system of the Gc protein in the Polish population was in good agreement with Hardy Weinberg equilibrium.
Using the method of isoelectric focusing on polyacrylamide gel, TfC subtypes were determined in 90 families with 173 children in 242 mother-child pairs. The results obtained have confirmed the hypothesis that transferrin phenotypes are determined by a single autosomal locus in which multiple alleles are situated.
Transferrin subtypes were determined by isoelectric focusing on a thin-layer polyacrylamide gel, using a mixture of ampholine of three pH ranges. In a sample of the Polish population numbering 361 subjects, six Tf subtypes dependent on three alleles Tfcc1, Tfcc2, Tfcc3 were encountered. They occurred with the following frequency: 0.744, 0.212, 0.044. It was found that Tf system in the Polish population was in a good agreement with Hardy Weinberg equilibrium.
Transferrin subtypes are considered to be some of genetic markers which can correlate with the incidence of certain diseases. The present study was designed to find out whether such a correlation is true for atopic dermatitis. Transferrin C subtypes (Tf CI, Tf C2, Tf C3) in blood serum were determined by the method of isoelectric focussing in polyacrylamide gel. Examinations were made in 30 atopic dermatitis patients. The control group was made up by a Polish population sample of 728 normal persons of both sexes. The results obtained were analysed statistically by means of test chi 2. There was no correlation between Tf C and atopic dermatitis (chi 2 = 0,638, d.f. = 2, 0,750 greater than p greater than 0,500).
