Abstract
A total of 1075 Russians from the Russian part of Karelia were genotyped at high-resolution for the human leukocyte antigen loci HLA-A, -B, -C, -DRB1, -DQB1, and -DPB1 using next generation sequencing methods. The haplotypic and allelic profiles as well as Hardy-Weinberg proportions of this population sample were evaluated. As the most frequent 6-locus haplotype, A*03:01?g?~?B*07:02?g?~?C*07:02?g?~?DRB1*15:01?g?~?DQB1*06:02?g?~?DPB1*04:01?g was identified with an estimated frequency of 3.5%. No deviation from Hardy-Weinberg Equilibrium was detected at any of the loci studied. The HLA genotypic data of the population sample reported here are available publicly in the Allele Frequencies Net Database under the population name "Russia Karelia" and the identifier AFN3430.

Abstract
Homozygous carriers of CCR5-?32, a gene variant of CC-type chemokine receptor 5 (CCR5), are highly resistant to infections with human immunodeficiency virus type 1 (HIV-1) and therefore preferred stem cell donors for HIV-infected patients. We analyzed CCR5 typing data of 1,333,035 potential hematopoietic stem cell donors enlisted with three national DKMS donor centers. Allele and genotype frequencies were determined for 87 countries of origin as self-assessed by the donors. CCR5-?32 allele frequencies ranged from 16.4% in the Norwegian sample to 0 in donors from Ethiopia. The highest CCR5-?32/?32 genotype frequency was found in the sample from the Faroe Islands (2.3%), whereas in 27 samples, predominantly of donors from Africa, Asia and South America, none of the individuals carried this genotype. The characteristic CCR5-?32 allele frequency decline from Northern to Southeastern Eurasia supports findings of earlier studies. With available HLA haplotype frequency information for the patient's ethnicity, our data allows upfront estimation of the probability that an HLA-matched donor with CCR5-?32/?32 genotype can be found for a patient in need of hematopoietic stem cell transplantation.
