Учитывая высокую вариабельность генов HLA и специфичность их аллельных спектров для разных популяций, представляло интерес провести HLA-типирование детей с изолированным СД 1 типа и в сочетании с АИТЗ (аутоиммунным полигландулярным синдромом 3а типа – АПС 3а типа) для установления аллелей, ассоциированных с предрасположенностью к развитию АИТЗ у детей с СД 1 типа в Беларуси. Определен спектр аллелей по 3 генам HLA-комплекса II класса (DRB1, DQB1, DQА1) у 49 детей с АПС 3а типа, 95 детей с СД 1 типа методом SBT (Sequence-Based Typing) и у 24 детей контрольной группы с помощью высокопроизводительного секвенирования нового поколения (Illumina). Выявлен ряд аллелей и гаплотипов DRB1, DQB1, DQА1, ассоциированных с предрасположенностью или резистентностью к обеим рассматриваемым формам аутоиммунной патологии (СД 1 типа и АПС 3а типа) у здорового детского контингента. Полученные данные свидетельствуют о наличии в белорусской популяции общего спектра полиморфных вариантов генов HLA II класса, вовлеченных в этиопатогенез СД 1 типа и АПС 3а типа. Вместе с тем у детей с АПС 3а типа обнаружена более высокая суммарная частота определенных подтипов аллеля HLA-DRB1*04 и одной из разновидностей гаплотипа DRB4-DQ4.3 по сравнению со сверстниками с изолированным СД 1 типа. Эти выявленные генетические маркеры могут быть использованы для выделения групп высокого риска развития АИТЗ у детей с СД 1 типа в белорусской популяции.</p></abstract><trans-abstract xml:lang="en"><p>Human leukocyte antigen (HLA) class II genes are one of the main genetic susceptibility factors of the most common autoimmune diseases, including type 1 diabetes mellitus (T1D) and autoimmune thyroid diseases (AITD). Distinct HLA alleles are associated with autoimmune endocrinopathies in different populations. This work was aimed to reveal the alleles associated with a predisposition to AITD in children with T1D in Belarus. 49 patients with a combination of T1D and AITD (autoimmune polyglandular syndrome type 3a – APS type 3a), 95 patients with T1D and 24 healthy controls were included into the study. HLA typing for 3 genes (DRB1, DQB1, DQА1) was performed by SBT (sequence-based typing) in the children with T1D and APS type 3a and by high-performance sequencing of a new generation (Illumina) in the children of the control group. We identified a number of alleles and haplotypes DRB1, DQB1, DQA1 associated with a predisposition or resistance to both forms of autoimmune pathology (T1D and APS type 3a) in healthy children. These data indicate a common spectrum of polymorphic variants of HLA class II genes involved in the etiopathogenesis of T1D and APS type 3 in the Belarusian population. At the same time, the children with type 3a APS had a higher total frequency of certain HLA-DRB1*04 allele subtypes and one of the variants of the DRB4-DQ4.3 haplotype, compared with the patients with isolated T1D. These revealed genetic markers can be used to identify high-risk groups of AITD in children with T1D in the Belarusian population.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>аутоиммунные заболевания щитовидной железы</kwd><kwd>сахарный диабет 1 типа</kwd><kwd>аутоиммунный полигландулярный синдром 3а типа</kwd><kwd>гены человеческого лейкоцитарного антигена</kwd><kwd>генетический полиморфизм</kwd></kwd-group><kwd-group xml:lang="en"><kwd>autoimmune thyroid diseases</kwd><kwd>type 1 diabetes</kwd><kwd>autoimmune polyglandular syndrome type 3a</kwd><kwd>human leukocyte antigen genes</kwd><kwd>genetic polymorphism</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Авторы выражают благодарность сотрудникам лабораторий нехромосомной наследственности и молекулярных основ стабильности генома Института генетики и цитологии НАН Беларуси, принявшим участие в исследовании.
