To give new insight into the huge polymorphism of HLA system and supplement the existing data, an analysis of HLA alleles and HLA-A~C~B~DRB1~DQA1~DQB1 haplotype distribution in 124 Albanian individuals from Kosovo was performed. All samples were HLA-typed applying the polymerase chain reaction-sequence specific oligonucleotide probing (PCR-SSOP) method and all ambiguous HLA typing results were additionally confirmed by the standard PCR-Sequence Specific Primers (PCR-SSP) high-resolution protocol. Twenty-two HLA-A, 21 HLA-C, 37 HLA-B, 27 HLA-DRB1, 11 HLA-DQA1 and 14 HLA-DQB1 allele groups were detected. Sixteen out of 172 different six-locus estimated haplotypes were found at a frequency higher than 1.00% with a cumulative frequency of 28.82%. The most prevalent haplotype was found to be HLA-A*02:01~C*07:01~B*18:01~DRB1*11:04~DQA1*05:05~DQB1*03:0(5.2%).A total of 13 haplotypes were observed with higher frequency than in populations reported in HaploStats and The Allele Frequency Net Database. The proposed origin of the most frequent haplotypes reflects a basic Euro-Mediterranean background of Albanians in Kosovo. This is the first report of high-resolution HLA-A~C~B~DRB1~DQA1~DQB1 haplotype distribution among the Albanian population from Kosovo, which provides valuable anthropological data and confirms population-specific characteristics. |
