Nine novel HLA-B alleles were detected during the routine HLA typing process.
Five novel HLA-B silent variants, HLA-B*08:01:81, HLA-B*18:01:59, HLA-B*35:01:82, HLA-B*35:03:45, and HLA-B*51:17:02, were detected by next-generation sequencing.
Six novel HLA-DRB1 alleles are described from bone marrow volunteers from the Russian Registry.
HLA-C*08:296 differs from HLA-C*08:02:01:01 by two nucleotide changes, one in an exon and one in an intron.
The novel HLA-B*40:01:92 allele differs from B*40:01:01:01 by a change of C → A in exon 5.
Characterisation of the novel HLA-B*35:636N allele in two bone marrow donors from the Russian State Registry.
Sequences of the novel HLA-C*02:31:02, -C*12:03:95, -C*12:03:96 and -C*17:03:06 alleles identified in Russian individuals.
Novel HLA-DQB1*06:03:54, HLA-DQB1*06:526 alleles and confirmatory HLA-DQB1*06:494 allele were detected during the HLA typing process.
Seven novel HLA-B alleles were detected during the routine HLA typing process.
Five novel HLA-DQB1 alleles, HLA-DQB1*02:01:51, -DQB1*03:390:02, -DQB1*03:573, -DQB1*04:105 and -DQB1*05:03:39 in Russian donors.
Five novel HLA-DRB1 alleles, HLA-DRB1*03:219, HLA-DRB1*04:171:02, HLA-DRB1*04:392, HLA-DRB1*11:01:52 and HLA-DRB1*11:342, were identified.
Identification of the HLA-C*01:287, HLA-C*03:710, HLA-C*04:543, HLA-C*08:304 and HLA-C*16:228 alleles and confirmation of HLA-C*02:249, HLA-C*04:532 and HLA-C*03:693.
HLA-A*03:505 contains a single nucleotide substitution at nucleotide position 236 (GAG to GCG).
Identification of five new HLA-A alleles by next-generation sequencing.
The novel HLA-DRB1*13:368 allele differs from HLA-DRB1*13:01:01:01 by one nucleotide substitution G → T in exon 3.
HLA typing of 9126 haematopoietic stem cell donors living in the Asian and European parts of Russia and identifying themselves as Russians was performed using NGS technology in 2-field resolution at the HLA-A, HLA-B, HLA-C, HLA-DRB1, and HLA-DQB1 loci. The study of donors in the Asian part of Russia disclosed 77 alleles at the HLA-A locus, 111 at the HLA-B locus, 58 at the HLA-C locus, 54 at the HLA-DRB1 locus, and 26 at the HLA-DQB1 locus. Donors of the European part of Russia are characterised by the following allelic diversity: 87 alleles at the HLA-A locus, 136 at the HLA-B locus, 72 at the HLA-C locus, 67 at the HLA-DRB1 locus, and 37 at the HLA-DQB1 locus. The most common five-locus haplotype in both populations is HLA-A*01:01 ~ HLA-C*07:01 ~ HLA-B*08:01 ~ HLA-DRB1*03:01 ~ HLA-DQB1*02:01. Throughout the study, 26 new alleles were revealed.
Two novel alleles, HLA-A*03:509 and HLA-C*05:308, were identified during routine next generation sequencing.
Three novel HLA-B alleles, HLA-B*08:336 N, HLA-B*18:258 N and HLA-B*51:425 N were identified in bone marrow donors.
