Рак молочной железы занимает лидирующие позиции по уровню заболеваемости во всем мире. Ген онкосупрессор PALB2 наряду с такими генами, как BRCA1, BRCA2, вовлечен в процессы репарации поврежденной ДНК. Частота встречаемости герминальных мутаций гена PALB2 при раке молочной железы и семейных случаях рака поджелудочной железы составляет приблизительно 1–2 % и 3–4 % соответственно. Представлен клинический случай 39-летней женщины, принадлежащей к якутской этнической группе, с диагнозом рак молочной железы с семейной историей рака поджелудочной железы. Материал и методы. Геномная ДНК выделена из периферической крови, ДНК-библиотеки приготавливали с использованием набора Hereditary Cancer Solution™ (Sophia Genetics, Швейцария) для изучения статуса 27 генов (ATM, APC, BARD1, BRCA1, BRCA2, BRIP1, CDH1, CHEK2, EPCAM, FAM175A, MLH1, MRE11A, MSH2, MSH6, MUTYH, NBN, PALB2, PIK3CA, PMS2, PMS2CL, PTEN, RAD50, RAD51C, RAD51D, STK11, TP53 и XRCC2). Секвенирование (2 × 150 п.н.) проводилось с использованием системы NextSeq 500 (Illumina, США). Результаты. По результатам биоинформатического анализа данных NGS у 39-летней женщины, принадлежащей к якутской этнической группе, с диагнозом рак молочной железы с семейной историей рака поджелудочной железы обнаружена новая герминальная мутация гена PALB2 со сдвигом рамки считывания (NM_024675: Exon1: c.47delA: p.K16FS). В соответствии с dbPubmed ClinVar новая мутация гена PALB2 расположена в том же кодоне, где ранее была описана, вероятно патогенная, мутация сайта сплайсинга (NM_024675.3: Exon1: c.48+1delG), вовлеченная в патогенез наследственных форм рака молочной железы и яичника. Заключение. Впервые у 39-летней женщины, принадлежащей к якутской этнической группе, с диагнозом рак молочной железы и с семейной историей рака поджелудочной железы обнаружена новая, вероятно патогенная, герминальная мутация гена PALB2 со сдвигом рамки считывания (NM_024675: Exon1: c.47delA: p.K16FS).</p></abstract><trans-abstract xml:lang="en"><p>Background. Breast cancer (BC) is the most common female malignancy worldwide. Partner And Localizer of BRCA2 gene (PALB2) is directly involved in DNA damage response. Germline mutation in PALB2 has been identified in breast cancer and familial pancreatic cancer cases, accounting for approximately 1–2% and 3–4%, respectively. The goal of this report was to describe new PALB2 mutation in a young Yakut breast cancer patient with family history of cancer. Material and Methods. Genomic DNA were isolated from blood samples and used to prepare libraries using a capture-based target enrichment kit, Hereditary Cancer Solution™ (SOP HiA GE NETICS , Switzerland), covering 27 genes (ATM, APC, BARD1, BRCA1, BRCA2, BRIP1, CDH1, CHEK2, EPCAM, FAM175A, MLH1, MRE11A, MSH2, MSH6, MUTYH, NBN, PALB2, PIK3CA, PMS2, PMS2CL, PTEN, RAD50, RAD51C, RAD51D, STK11, TP53 and XRCC2). Paired-end sequencing (2 × 150 bp) was conducted using NextSeq 500 system (Illumina, USA ). Results. Here we describe a case of a never-before-reported mutation in the PALB2 gene that led to the early onset breast cancer. We report the case of a 39-year-old breast cancer Yakut woman with a family history of pancreatic cancer. Bioinformatics analysis of the NGS data revealed the presence of the new PALB2 gene germinal frameshift deletion (NM_024675:exon1:c.47delA:p.K16fs). In accordance with dbPubMed ClinVar, new mutation is located in codon of the PALB2 gene, where the likely pathogenic donor splice site mutation (NM_024675.3:c.48+1delG) associated with hereditary cancer-predisposing syndrome has been earlier described. Conclusion. We found a new never-before-reported mutation in PALB2 gene, which probably associated with early onset breast cancer in Yakut indigenous women with a family history of pancreatic cancer.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>наследственные мутации</kwd><kwd>рак молочной железы</kwd><kwd>этносы России азиатского происхождения</kwd><kwd>якуты</kwd><kwd>PALB2</kwd></kwd-group><kwd-group xml:lang="en"><kwd>germline mutation</kwd><kwd>breast cancer</kwd><kwd>Asian ancestry ethnic groups in Russia</kwd><kwd>Yakut</kwd><kwd>PALB2</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при финансовой поддержке РНФ, проект № 22-25-20032; Оборудование ЦКП «Медицинская геномика» Томского НИМЦ.</funding-statement><funding-statement xml:lang="en">The study was funded by the Russian Science Foundation, project № 22-25-20032; The Core Facility «Medical genomics», Tomsk NRMC.</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">Gifoni A.C.L.V.C., Gifoni M.A.C., Wotroba C.M., Palmero E.I., Costa E.L.V., Dos Santos W., Achatz M.I.
