“…, North Africans, sub-Saharans, Caucasian populations, and Saudi Arabians(24). The B*44 allele group (B*4402 af = 0.03; B*440301 af = 0.07) and the B*4501 (af = 0.068), B*0801 (af = 0.061) alleles also occurred frequently in the CH group, as reported also for other Moroccan populations.Comparing the frequencies of B*51, B*58, and B*35 allele groups with other populations, we found a low incidence of B*510101 (af = 0.041) in CH, as observed also in ME, in comparison with Moroccans from Casablanca and ElJ, other North African and Mediterranean populations.…”

“…As observed with HLA‐A locus, there were many HLA‐B variants in this population. Out of 42 allelic variants, the most frequently identified belongs to B*50 group (B*5001 af = 0.110; B*5002 af = 0.014), with a higher incidence in comparison with other Moroccans, except for Morocco Casablanca (7), North Africans, sub‐Saharans, Caucasian populations, and Saudi Arabians (24). The B*44 allele group (B*4402 af = 0.03; B*440301 af = 0.07) and the B*4501 (af = 0.068), B*0801 (af = 0.061) alleles also occurred frequently in the CH group, as reported also for other Moroccan populations.…”

Correlation between genetic HLA class I and II polymorphisms and anthropological aspects in the Chaouya population from Morocco (Arabic speaking)

et al. 2010

The aim of this study was to provide genetic and anthropological information on the Chaouya (CH), an Arabic-speaking population living in West Morocco, Atlantic coast (Settat). In 98 unrelated healthy CH volunteers, we first investigated the human leukocyte antigen (HLA) class I and II allele polymorphisms using a sequence-based typing method and examined haplotypes and relatedness of this group to other African and Mediterranean populations. The study showed the close relatedness with Tunisian population and other North Africans, together with a strong influence of various immigrations, mainly Spaniards, French, and Portuguese, as expected. Nevertheless, analysis of class II allele frequencies (afs) showed that Oromo and Amhara Ethiopian groups cluster together with the Berbers and other North Africans, confirming the relationship between these populations (Afro-Asiatic linguistic group, Hamites). South and sub-Saharan Africans cluster separately at a great distance from CH, except the sub-Saharan Bantu population from Congo Kinshasa, which shows a relatively close genetic relationship ascribable to the effect of a diversifying selection. On the other hand, considering HLA class I afs analyses, it was noteworthy that CH grouped together with sub-Saharans, showing a close genetic distance mainly with Ugandas and Kenians Luo.

HLA‐A,B,C and DR antigens in a sample of the Tunisian population

et al. 1987

View full text Add to dashboard Cite

The HLA-A, B and DR phenotypes of 109 unrelated Tunisian individuals have been determined. The HLA-A and B antigen frequencies were compared with data reported for European Caucasoids and various Arab populations.Most similarities in antigen frequencies were seen between Tunisians and Kabyles from North Africa. A high frequency of HLA-A23 and HLA-BwSO was observed in Tunisians and all Arab populations. A very close similarity in HLA-DR antigen frequencies exists between Tunisians and European Caucasoids. Linkage disequilibria between alleles of HLA loci were examined; many instances of previously reported antigen associations were seen in Tunisians, together with a number o , f associations which have not been described elsewhere. Aw34B8 and A2DRw14 are suggested as being common haplotypes in Tunisians.

“…Comparisons of the HLA antigen frequencies in Saudi Arabs with other Arab populations are also summarized in Table 3. These comparisons are limited to studies of Moslem Arabs resident in Israel (Bodmer et al 1972), Iraqis (Jabbar & Dick 1976), expatriate Lebanese resident in Sydney, Australia (Bashir et al 1973) and different religious groups in the Lebanon (Serre et al 1979). The Lebanese in Bashir's study were all Christians and therefore might possibly not be a true representation of the whole population.…”

HLA polymorphisms in Saudi Arabs

et al. 1985

The HLA‐A, ‐B, ‐C, ‐DR, Bf and GLO phenotypes of 109 unrelated Saudi Arab males have been determined. HLA‐A and ‐B antigen frequencies were compared with data reported for European Caucasoids and various Arab populations. Most similarities in antigen frequencies were seen between Saudi Arab and Iraqi populations. A high frequency of Bw50 was observed in Saudi Arabs. The frequencies of HLA‐DR antigens in Saudi Arabs were compared to European Caucasoids. HLA‐DR7 was at high frequency in Saudi Arabs. Linkage disequilibria between alleles of HLA loci was examined. Many instances of previously reported antigen associations were seen in Saudi Arabs, together with a number of associations which have not been described elsewhere. HLA‐Cw6‐Bw50‐DR7‐BfS0.7 is suggested as being a common haplotype in Saudi Arabs.

HLA‐Antigen Frequency in an Iraqi Population

Abstract: The frequencies of HLA‐A and ‐B locus antigens in a group of 64 individuals from Iraq are reported. The frequencies are in broad agreement with those previously reported for Arabs, but show differences from Persian frequencies.
