Высокополиморфные HLA-гены демонстрируют выраженное неравновесное сцепление между собой, что приводит к формированию мультилокусных HLA-гаплотипов. Оценка разнообразия HLA-гаплотипов в популяции важна при трансплантации аллогенных гемопоэтических стволовых клеток. Золотым стандартом для изучения HLA-гаплотипов являются семейные исследования. HLA-гаплотипы, полученные на основе наблюдений за сегрегацией HLA-аллелей в пределах семьи, реально существуют в человеческой популяции. Цель работы – установление частот HLA-A-B-C-DRB1-DRB3/DRB4/DRB5-DQA1-DQB1-DPA1-DPB1-гаплотипов в семьях больных с назначением к HLA-типированию для проведения трансплантации аллогенных гемопоэтических стволовых клеток. Исследование включало 109 семей больных с заболеваниями системы крови, в которых больным и членам их семей было назначено HLA-типирование для поиска донора аллогенных гемопоэтических стволовых клеток. Больные и члены семей были типированы методом NGS в лаборатории тканевого типирования ФГБУ «НМИЦ гематологии» Минздрава России по 11 HLA-генам – A, B, C, DRB1, DRB3, DRB4, DRB5, DQA1, DQB1, DPA1 и DPB1 методом секвенирования следующего поколения с помощью AllType FastPlex NGS Amplification Kits (One Lambda, США). Полученные последовательности анализировались при помощи компьютерной программы TypeStream Visual Software (TSV) и базы данных IPD-IMGT/HLA 3.44. В исследованных семьях было установлено 360 копий HLA-гаплотипов. Частоты HLA-гаплотипов определялись прямым подсчетом. Наиболее распространенным 7-локусным гаплотипом являлся A*01:01-B*08:01-C*07:01-DRB1*03:01-DRB3*01:01-DQA1*05:01-DQB1*02:01/163N, наиболее распространенным 9-локусным гаплотипом – A*03:01-B*07:02-*07:02-DRB1*15:01-DRB5*01:01-DQA1*01:02-DQB1*06:02-DPA1*01:03-DPB1*04:01P. Эти HLA-гаплотипы в варианте A-B-C-DRB1-DQB1 являются первым и вторым по распространенности HLA-гаплотипами в большинстве российских регистров доноров костного мозга. Несмотря на некоторые отличия, распределение HLA-гаплотипов в семьях больных и в российских регистрах обладает схожестью, поэтому вероятность найти совместимого донора для больных с распространенными HLA-гаплотипами в российских регистрах достаточно велика. Из-за горячей точки рекомбинации большинство 7-локусных гаплотипов соединяются в 9-локусных гаплотипах с различными аллелями генов локуса HLA-DP, однако проведенное исследование выявило существование сильного неравновесного сцепления между HLA-аллелями DRB1*03:01 и DPB1*01:01P (D` = 0,579), DRB1*07:01 и DPB1*17:01 (D` = 0,808), DRB1*09:01 и DPB1*04:02P (D` = 0,502). Полученные знания о реальных 7- и 9-локусных HLA-гаплотипах, существующих в семьях больных с назначением к трансплантации аллогенных гемопоэтических стволовых клеток, могут быть использованы в клинической практике в качестве референсных для анализа результатов HLA-типирования и предсказания ожидаемых HLA-гаплотипов. Показано, что, несмотря на существование горячей точки рекомбинации между локусом HLA-DP и остальным комплексом HLA-генов, наблюдается сильное неравновесное сцепление между некоторыми аллелями генов DRB1 и DPB1.</p></abstract><trans-abstract xml:lang="en"><p>HLA haplotype is a block of HLA genes located on the same chromosome. Highly polymorphic HLA genes display strong linkage disequilibrium, which results in conserved multilocus HLA haplotypes. Assessment of HLA haplotypic diversity of a specific population is important, particularly for allogeneic hematopoietic stem cell transplantation. Family pedigrees remain the gold standard for studying HLA haplotype segregation. HLA haplotypes, obtained by observations of the segregation of HLA alleles within the family, really exist in the human population. The aim of this work has been to establish the frequencies of HLA haplotypes A-B-C-DRB1-DRB3/DRB4/DRB5-DQA1-DQB1-DPA1-DPB1 in families of patients with assignment to HLA-typing for allogeneic hematopoietic stem cell transplantation. The study included 109 families of patients, in which patients and their potential relative donors of allogeneic hematopoietic stem cell were subjected to HLA-typing. Patients and members of their families were typed by the NGS method in the Laboratory of Tissue Typing at the National Medical Research Center for Hematology for 11 HLA genes – A, B, C, DRB1, DRB3, DRB4, DRB5, DQA1, DQB1, DPA1 and DPB1. The genotyping was performed by the NGS method using the AllType NGS 11 Loci Amplification Kits (One Lambda, USA) on the MiSeq sequencing platform (Illumina, USA). The sequences were analyzed using the TypeStream Visual Software (TSV) (One Lambda, USA) and the IPD-IMGT/HLA database 3.44. 360 copies of HLA-haplotypes were found in the studied families. The frequencies of HLA haplotypes were determined by direct counting. The most common 7-locus haplotype was A*01:01-B*08:01-C*07:01-DRB1*03:01-(DRB3*01:01-DQA1*05:01)-DQB1*02:01/163N, the most common 9-locus haplotype was A*03:01-B*07:02-C*07:02-DRB1*15:01-DRB5*01:01-DQA1*01:02-DQB1*06:02-DPA1*01:03-DPB1*04:01P. These HLA haplotypes (in brief, A-B-C-DRB1-DQB1) are the first and second most common HLA haplotypes in most Russian registries of bone marrow donors. Despite several differences, the distribution of HLA haplotypes in families of the patients and in donor registries is similar, and the probability of finding a compatible donor for patients with common HLA-haplotypes in Russian registries is quite high. Most of 7-locus haplotypes are associated with different alleles of the HLA-DP locus in the 9-locus haplotypes, due to presence of a recombination hot spot. The study revealed strong linkage disequilibrium between the HLA alleles DRB1*03:01 and DPB1*01:01P (D’ = 0.579), DRB1*07:01, and DPB1*17:01 (D’ = 0.808), DRB1*09:01 and DPB1*04:02P (D’ = 0.502). The information obtained about real 7- and 9-locus HLA-haplotypes in families may be used in clinical practice as a reference for analyzing the results of HLA-typing and predicting the expected HLA-haplotypes. It has been shown that, despite recombination hot spot between the HLA-DP locus and the rest of the HLA complex, there is strong linkage disequilibrium between some alleles of the DRB1 and DPB1 genes.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>HLA-гаплотип</kwd><kwd>семьи</kwd><kwd>неравновесное сцепление</kwd><kwd>HLA-DPB1</kwd><kwd>трансплантация</kwd><kwd>секвенирование следующего поколения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>HLA haplotype</kwd><kwd>families</kwd><kwd>linkage disequilibrium</kwd><kwd>HLA-DPB1</kwd><kwd>transplantation</kwd><kwd>next-generation sequencing</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Авторы выражают благодарность всем сотрудникам ФГБУ «НМИЦ гематологии» Минздрава России, занимающихся трансплантацией аллогенных гемопоэтических стволовых клеток у больных с заболеваниями системы крови, без которых это исследование было бы неосуществимо.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Бубнова Л.Н., Кузьмич Е.В., Павлова И.Е., Беляева Е.В., Терентьева М.А.
