Population genetic studies in Saudi Arabia are performed for EsD, GPT, AcP, ADA, AK, 6-PGD, PGM, C3, Tf, Hp, Gc, Pi, Bf, Hb, ABO-blood groups and Rh-factor, level of the third component of complement and immunoglobulins. The data are compared with reported frequencies in European and African populations.

The phenotypic frequencies of 24 polymorphic blood markers in a sample of patients with Huntington's disease (HD) have been compared with those in a sample of healthy Australian volunteers in an effort to detect any associations between HD and the markers concerned. The Rh factor, c, has a significantly lower frequency in the HD sample while ACP1c and Gm1,2 have a significantly higher frequency. The linkage relations of the HD locus have been analysed with respect to the various marker loci concerned. This analysis involved the development of methods to overcome the general lack of genetic data concerning the affected parent and the possibility that presently unaffected offspring may be asymptomatic carriers of the HD gene. The results suggest that close linkage between the HD locus and Fy, ADA, ACP1, Gc or Bg is highly unlikely. They also suggest a low probability of close linkage to ABO, Rh, Jk, Lu, AK1, PGM1 or C3. Positive linkage scores were obtained for P, Hp and Gm. The results are inconclusive for MNSs, K, Le, Se, GPT and Inv. The available data were uninformative for linkage between the HD locus and Co, 6-PGD or E1.

Linkage analysis of Lu and Se and 31 other loci indicate that Lu:Se are not closely linked to ABO, ACP1, Co, Do, Est.D,Fy, GC, Gm, GLO:HLA, GPT, Inv, Jk,K,MN,P,PGD,PGM1, Rh,Sc, UMPK OR Yt. Lod scores for 18 families informative for Lu:Se gave no evidence for sex differentiation in recombination fraction: theta for males was 0.07, and for females, .08.

In a series of 726 random Caucasian adults tested with anti-Coa and anti-Cob allele frequencies were Coa 0.9470, Cob 0.0530. The distribution of Colton phenotypes in 205 children of 57 selected families was in accordance with expectation. A linkage analysis of Co and 26 other loci indicates that Co is not closely linked to AcP1, ABO, AK1, Ch, Do, GLO, Gm, GPT, HLA, Hp, K, Lu, MN, PGM1 or Rh and does not lie between PGD and PGM1 on chromosome 1.

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 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.

In the present paper we report on new data of the frequency of common and rare variants in the Italian population for ADA, AK-1, 6-PGD, EsA, EsB, EsD, PGM-1, PGM-2, SOD-A, AcP, GPT, and PGI. Moreover we present a comprehensive review of the available data on the electrophoretic variants of red cell enzymes in Italians. We find a considerable degree of genetic heterogeneity between the various populations living in the Peninsula and between the population of the Peninsula and of Sardinia. We also find that the estimates of the average heterozygosity are considerably smaller for the population of Sardinia as compared to Peninsula and Sicily. Finally, we report on the occurrence of several uncommon enzyme variants, which overall frequency is very similar to previously reported estimates for North European populations (Harris et al. 1974).

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.
