Population genetic studies of Shuara Indians in Ecuador are performed for GPT, AP, PGM1, Ak, EsD, 6-PGD, Hp, Gc, C3, Bg, ChE, Tf, Pi, Bf phenotypes, IgG, IgA, IgM, C3, C3-proactivator, C4 levels and acetylator phenotypes. Some systems having a polymorphism in many other populations showed a lack of some of those alleles in the population under study (C3, ChE, Tf, AK and almost absent 6-PGD, Bg, Bf).

The phenotypes of 56 families with 126 children from the Hamburg area as well as gene frequencies and segregation of the genetic markers GPT, AP, ADA, AK, PGM1, PGM3, 6-PGD, CHE, C3, Gc, Tf, Hp and Cp were studied. In regard to linkage, the informative families were correlated to the results of HL-A and GPT typing. The linkage was tested according to the sequential test by MORTON (1955). See article. For other gene loci, linkage to the HL-A or GPT system could not be proved. But the positive lod scores of HL-A/GPT, HL-A/AP and GPT/6-PGD may give indication for linkage.

The kinship analysis of seven genetic systems in the province of Ferrara permits some considerations on the possible chronology of emergence of their polymorphisms in the area. It is proposed that, assuming neutrality of these systems, and under several restrictions, the emergence by migration of the polymorphisms in the seven systems ACP, ESD, GLO, GPT, PGD, PGM1, PGP might have had the following sequence: PGP and GLO and possibly PGD; PGM1 and GPT; ACP and ESD. All polymorphisms must be older than the beta-thalassemia polymorphism in the area.

A genetic study was carried out on phenotype and gene frequencies of the genetic markers in eight red cell enzymes: glyoxalase I (GLO1), glutamic pyruvate transaminase (GPT), phosphoglucomutase (PGM1), esterase D (ESD), adenylate kinase (AK1), 6-phosphogluconate dehydrogenase (6-PGD), adenosine deaminase (ADA), acid phosphatase (ACP1), in the Hungarian ethnic group living in Yugoslavia. The gene frequencies obtained were: GPT*1 = 0.542, PGM1*1 = 0.760, ESD*1 = 0.909, AK*1 = 0.971, PGD*A = 0.971, ADA*1 = 0.939, GLO1*1 = 0.417, ACP1*A = 0.329, ACP1*B = 0.591 and ACP1*C = 0.080. The distribution of these phenotype and gene frequencies was examined and compared with the phenotype and gene frequencies found for the Hungarian population living in Hungary and for other populations living in the northeast of Yugoslavia.

A wide data collection on blood group gene frequencies in Italian regions and provinces is presented. This report is the result of a joint collaboration of human geneticists and forensic haematologists started in 1979 and updates a previous work by the same group. The following genetic polymorphisms have been examined: red-cell antigens (ABO, FY, Kell, Kidd, Lewis, Lutheran, MNSs, P, Rhesus), red-cell enzymes (ACP1, ADA, AK1, ESD, GLO1, GPT, PGD, PGM1), plasma proteins (BF, C3, GC, HP, IGK, PI, TF). Data have been classified according to genetic systems, Italian regions and provinces. Gene frequencies were estimated by the maximum likelihood method. The goodness of fit to Hardy-Weinberg proportions has been evaluated by the likelihood ratio statistics. Genetic heterogeneity of provinces and regions is reported.

Two population groups in South Korea, one from Kwangju and one from Kangreung, were studied in regard to the erythrocyte enzyme polymorphisms GPT, ACP, GLO, ESD, 6PGD, ADA, AK, PGP and subtypes of PGM1 as well as regarding the serum protein variants of C3, HP, BF, PLG, AMY and the subtypes of GC, TF and PI. The results were compared with data of the population groups from the area of Cheju Island, Taejon and Seoul. The Korean population showed a rather high degree of genetic homogeneity.

The genetic structure of the population of Ferrara Province in the Po delta in Italy was investigated using chi 2 analysis, kinship analysis, analysis of correspondences, and geographical mapping of principal components of gene frequencies. chi 2 Analysis tests for Hardy-Weinberg equilibrium and for heterogeneity of gene and phenotype frequencies; kinship analysis tests for association between indicators of genetic and geographic proximity; analysis of correspondences relates localities and genetic systems in an eigenvectorial space; and geographic mapping displays the principal components of gene frequencies in the real space. In 1,364 adults in 26 residential units, seven presumably neutral isoenzyme systems were typed; ACP1 ESD, GLO I, GPT, PGD, PGM1 and PGP. It was found that average kinship for these neutral systems is correlated with geographic distance in this small area, but not as strongly as kinship for beta-thalassemia. A north-south gradient was observed for ESD. Analysis of correspondences indicated GPT, PGM1, and GLO I as the systems contributing most to differentiation within the province. The maps obtained from principal components of gene frequencies were consistent with the migrational history of the area.

We conducted genetic linkage analyses of breast cancer in 20 pedigrees, each having at least one case of bilateral breast cancer diagnosed before 50 years of age. We tested for linkage using inheritance models from previous segregation analyses, incorporating differences in risk based on menopausal status into the analyses. We tested for heterogeneity by predividing the data set based on the interval between diagnoses of the proband's two primaries (less than 1 year (synchronous) versus at least 2 years (asynchronous], and on the histological types of breast cancer in the pedigrees. Very tight linkage could be excluded between breast cancer and ABO, GC, GPT, MNS, and PGM1 for some of the different linkage analyses. A maximum lod score of +1.01 (at theta = 0.001) between ACP1 and a breast cancer susceptibility locus was seen in the asynchronous all-cases subsample.

Linkage analyses were performed in a single large family with multiple endocrine neoplasia, type 2 (MEN-2) between 23 classical genetic polymorphisms and MEN-2. We exclude close linkage of the locus for MEN-2 with ABO, ACP1, BF, ESD, Fy, GALT, GLO1, Jk, MNSs, P, PGM1, Rh and TF, as well as absolute linkage with GPT. These results raise to about 6% the proportion of the genome that has been excluded in this one family. Somewhat positive lod scores were obtained for GC (0.92 at theta = 0), GPT (0.73 at theta = 0.1) and HP (1.49 at theta = 0.05); although not statistically significant, these findings suggest regions of the genome that warrant additional study.

Linkage data on human factor H (HF) and 22 other human genetic markers are presented. Close linkage at theta less than 0.10 can be ruled out for a series of marker systems (Rh, PGM1, ACP1, Jk, Tf, Gc, MNSs, ME2, HLA, GLO1, ORM, Gt, PI, Hp, GPT). Strong evidence for linkage was obtained for peptidase A (PEPA) with lods greater than 3.0 at theta = 0.10 in males and at theta = 0.20 for the sexes combined. From this result the HF locus can be provisionally assigned to chromosome 18.
