Болезнь Ниманна–Пика, тип А (БНП, тип А) является наиболее тяжёлой формой дефицита кислой сфингомиелиназы — редкого наследственного заболевания, обусловленного биаллельными патогенными вариантами в гене SMPD1. С 2023 года для лечения пациентов с болезнью Ниманна–Пика в России применяется ферментная заместительная терапия препаратом олипудаза альфа, которая, однако, не изменяет прогноз течения для неврологических форм. Единственным эффективным видом помощи при системных проявлениях заболевания у пациентов с БНП, тип А наряду с симптоматической терапией является трансплантация гемопоэтических стволовых клеток. Ранняя лабораторная диагностика играет решающую роль для своевременной постановки диагноза и назначения терапии у пациентов с этой формой заболевания.</p><p>Цель исследования — описать внутрисемейный полиморфизм клинической симптоматики БНП, тип А на примере двух сибсов из одной семьи.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Клиническое наблюдение и диагностика проводились на базе ФГАУ «НМИЦ здоровья детей» Минздрава России в одной семье. Активность кислой сфингомиелиназы измерялась в сухих пятнах крови методом высокоэффективной жидкостной хроматографии и тандемной масс-спектрометрии (ВЭЖХ-МС/МС); нуклеотидные варианты в гене SMPD1 выявлялись методом секвенирования по Сэнгеру. Семейный сегрегационный анализ был выполнен для восьми членов семьи.</p></sec><sec><title>Результаты</title><p>Результаты. Диагностика пробанда выявила значительное снижение активности кислой сфингомиелиназы в сухих пятнах крови пациента, а также наличие биаллельных каузальных вариантов c.996del (p.Phe333Serfs*52) и c.1252C&gt;T (p.Arg418*) в гене SMPD1, унаследованных от родителей. Диагностика больного сибса была выполнена уже на вторые сутки жизни, подтвердив тем самым лабораторный диагноз БНП, тип А. В результате своевременно установленного диагноза назначена трансплантация костного мозга, определившая дальнейший прогноз для жизни ребёнка.</p></sec><sec><title>Заключение</title><p>Заключение. На примере двух сибсов из одной семьи продемонстрирован полиморфизм клинической симптоматики БНП, тип А. Показано, что ранняя диагностика данной формы заболевания значительно улучшает прогноз и даёт возможности для своевременного начала терапии.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Niemann-Pick disease type A (NPD type A) is the most severe form of acid sphingomyelinase deficiency, a rare inherited disorder of the lysosomal storage disorders with autosomal recessive inheritance caused by biallelic pathogenic variants in the SMPD1 gene. Since 2023, enzyme replacement therapy with olipudase alfa has been used to treat patients with NPD in Russia. This therapy does not alter the prognosis for neurological forms of the disease, as it does not penetrate the blood-brain barrier. Therefore, the only effective treatment, along with symptomatic therapy, for the systemic manifestations of NPD type A is hematopoietic stem cell transplantation, which does not prevent central nervous system damage. Early laboratory diagnostics using biochemical and molecular genetic diagnostic methods are crucial for timely diagnosis and treatment of patients with this form of the disease.</p></sec><sec><title>Aim</title><p>Aim: to describe intrafamilial polymorphism of clinical symptoms of NPD, type A using the example of two siblings from the same family.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Clinical observation and diagnostics were conducted at the National Medical Research Center for Children’s Health of the Russian Ministry of Health from 2012 to 2026 in a single family in which the first proband with clinical symptoms characteristic of NBP type A was identified in 2012. Acid sphingomyelinase activity was measured in dried blood spots using tandem mass spectrometry, and nucleotide variants in the SMPD1 gene were identified using Sanger sequencing. Familial segregation analysis was performed for the proband and eight family members.</p></sec><sec><title>Results</title><p>Results. Diagnosis of the first proband revealed a significant decrease in acid sphingomyelinase activity in the patient’s spinal cord. Sequencing revealed the presence of two pathogenic heterozygous variants in the SMPD1 gene: c.996del (p.Phe333Serfs52) and c.1252C&gt;T (p.Arg418). Carriage of the pathogenic causative variants in the SMPD1 gene was confirmed in the parents. The second proband was diagnosed on the second day of life. As a result of the timely diagnosis, immunotherapy (bone marrow transplant) was prescribed, which determined the child’s prognosis.</p></sec><sec><title>Conclusion</title><p>Conclusion. Using two siblings from the same family as an example, polymorphism in the clinical symptoms of NPD type A was demonstrated. Early diagnosis of this form of the disease significantly improves the prognosis and enables timely initiation of therapy.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>лизосомные болезни накопления</kwd><kwd>болезнь Ниманна–Пика</kwd><kwd>тип А</kwd><kwd>сфингомиелиназа</kwd><kwd>клиническая картина</kwd><kwd>ген SMPD1</kwd><kwd>трансплантация гемопоэтических стволовых клеток</kwd></kwd-group><kwd-group xml:lang="en"><kwd>lysosomal storage disease</kwd><kwd>Niemann-Pick disease type А</kwd><kwd>sphingomyelinase</kwd><kwd>clinical picture</kwd><kwd>SMPD1 gene</kwd><kwd>hematopoietic stem cell transplantation</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Schuchman EH, Wasserstein MP.
