Синдром Барде-Бидля - аутосомно-рецессивное заболевание, характеризующееся ожирением, пигментной дегенерацией сетчатки, полидактилией, задержкой психоречевого развития и структурными повреждениями почек. В работе представлены результаты применения МПС-панели, включающей кодирующие последовательности и прилегающие интронные области 21 гена, ассоциированного с синдромом Барде-Бидля. Впервые была проведена молекулярно-генетическая диагностика в группе из сорока российских пациентов с синдромом Барде-Бидля из неродственных семей. В результате исследования удалось подтвердить диагноз молекулярно-генетическим методом у 40% пациентов (n=16). В генах BBS1, BBS7 и BBS10 встретились повторяющиеся варианты. Частота встречаемости патогенных и вероятно патогенных вариантов в генах BBS1 и BBS10 у российских пациентов соответствует зарубежным данным. Варианты в гене BBS7 встретились у пяти человек, у четырех из них был обнаружен патогенный вариант c.1967_1968delTAinsC, не встречающийся в других популяциях. Результаты, представленные в статье, показывают значительный вклад в заболеваемость синдромом Барде-Бидля в российской популяции патогенных вариантов в гене BBS7. Bardet-Biedl syndrome is an autosomal recessive disorder characterized by obesity, retinitis pigmentosa, polydactyly, development delay, and structural kidney defects. This study shows the results of using an MPS panel that includes coding sequences and intronic areas of 21 genes associated with Bardet-Biedl syndrome. For the first time molecular genetic testing has been provided for the group of 40 Russian patiens with Bardet-Biedl syndrome from unrelated families. As a result of the testing, diagnoses were confirmed for 40% of the patients (n=16). The genes BBS1, BBS7, BBS10 had recurrent variants. The frequency of pathogenic and likely pathogenic variants in the genes BBS1 and BBS10 among Russian patients matches the research data in other countries. Variants in the BBS7 gene were found for five people, four of them had a pathogenic variant c.1967_1968delTAinsC, which is not present among other populations. Results provided in this article show the significant role of pathogenic variants in the BBS7 gene in patients with Bardet-Biedl syndrome in Russian population.

Summary Molecular genetic testing is part of modern medical practice. DNA tests are an essential part of diagnostics and genetic counseling in single gene diseases, while their application in polygenic disorders is still limited. Pharmacogenetics studies DNA variants associated with variations in drug efficacy and toxicity, and tests in this field are being developed rapidly. The main method for molecular genetic testing is the polymerase chain reaction, with a number of modifications. New methods, such as next generation sequencing and DNA microarray, should allow simultaneous analysis of a number of genes, even whole genome sequencing. Ethical concerns in molecular genetic testing are very important, along with legislation. After molecular genetic testing, interpretation of results and genetic counseling should be done by professionals. With the example of thrombophilia, we discuss questions about genetic testing, its possibilities and promises.

Background: Acne is a multifactorial disease, in the pathogenesis of which one of the leading factors is the excessive effect of androgens on the hair follicles (HFs) and sebaceous glands (SGs), along with hypersecretion of sebum, pathological follicular hyperkeratosis and an inflammatory response. The search for genotypic markers in patients with varying severity of acne is a difficult task due to the multifactorial pathogenesis and the role of trigger factors in the formation of acne. The aim of this study was to determine SNPs within 3 genes involved in steroidogenesis (MVK, ARPC1B, and CA2) in patients with severe acne. Methods and Results: The study included 70 patients (42 men and 28 women) aged between 15 and 46 years (the median age - 22.1 years). The main group (MG) included 50 patients (29 men and 21 women) with severe acne. The control group (CG) consisted of 20 apparently healthy individuals (13 men and 7 women). Molecular-genetic diagnostics was carried out by the method of high-throughput DNA sequencing (next-generation sequencing). Our study showed that severe acne is associated with 12 polymorphic loci of the MVK gene (4 SNPs in exons and 8 SNPs in introns), 7 SNPs of the ARPC1B gene (2 SNPs in exons and 5 SNPs in introns), and 9 SNPs of the CA2 gene (3 SNPs in exons and 6 SNPs in introns). Conclusion: The revealed features of the SNPs within the MVK, ARPC1B, and CA2 genes in patients with severe acne probably indicate a hereditary determination of steroidogenesis in acne.

Abstract: Next generation sequencing methods represent the latest era of molecular genetic diagnostics. After a general introduction on primary immunodeficiencies, the author summarizes the importance of molecular genetic studies, especially next generation sequencing in the diagnosis of primary immunodeficiencies. Another purpose of the manuscript is to give a brief summary on the methodological basis of next generation sequencing. The author analyzes the advantages and disadvantages of primary immunodeficiency gene-panel sequencing and whole-exome and whole-genome sequencing. Primary immunodeficiency genes and diseases recognized by next generation sequencing is also summarized. Finally, the author emphasizes the indispensability of gene level diagnostics in primary immunodeficiencies and presents the results achieved in this field in Hungary.

The analysis of legal base of genetic researches in clinical practice is carried out. Modern standards of medical care are analyzed. The list of the diseases and pathological states demanding performance of genetic researches is made. The list of the medical services connected with genetic researches is also made. It is shown, that genetic researches make 10% of the nomenclature of medical services. From them about 60% medical services provide diagnosis of somatic pathology, the others are directed to identification of nucleinic acids of causative agents of infectious and parasitic diseases. Genetic researches are carried out mainly at a stage of specialized and primary medical care. Genetic researches are included in20% of standards of medical care. Genetic researches are conducted concerning 15 classes of diseases. More often genetic researches are conducted for diagnosis of the latent infections, enzimopatiya, hereditary diseases of a metabolism, and also cancer. There are some problems of cytogenetic and molecular genetic diagnostics in hospitals. Genetic researches are complex and expensive. Interpretation of the received results is difficult. It is necessary to develop standards of genetic researches. It is necessary to improve legal base of genetic researches.
