Experience with Molecular Diagnosis in 48 Cases of Neonatal Diabetes Mellitus Using Targeted Next-Generation Sequencing

Tikhonvich Yulia , Vasilyev Evgeny , Petrov Vasily , Malievsky Oleg , Petryaikina Elena , Ribkina Irina , Stotikova Olga , Tiulpakov Anatoly

Background: Neonatal diabetes mellitus (NDM) comprises a group of monogenic disorders caused by mutations in genes involved in pancreatic development or insulin secretion. Accurate and rapid molecular diagnosis of NDM is pivotal for making decision on the treatment strategy. Next-generation sequencing (NGS) allows simultaneos analysis of several candidate genes, which facilitates the diagnostic procedure in NDM.Objective and hypotheses: To summarise our ...

Targeted Next-Generation Sequencing Demonstrates High Frequency of ‘Dyshormonogenesis Genes’ Mutations in Severe Congenital Hypothyroidism

Makretskaya Nina , Bezlepkina Olga , Kolodkina Anna , Kiyaev Alexey , Vasilyev Evgeny , Petrov Vasily , Kalinenkova Svetlana , Duhoreva Olga , Malievsky Oleg , Dedov Ivan , Tiulpakov Anatoly

Background: 80–85% of cases of congenital hypothyroidism (CH) are shown to be due to thyroid dysgenesis, while 15–20% are due to dyshormonogenesis. At least 12 candidate genes are associated with congenital hypothyroidism (CH), however its molecular basis is defined in fewer than 10% of the patients (ESPE consensus, 2014). Recent studies suggest that using a next generation sequencing (NGS) approach may increase the mutation yield in CH.Objecti...

GH Excess in McCune–Albright Syndrome

Tessaris Daniele , Boyce Alison M , Matarazzo Patrizia , Lala Roberto , Collins Michael T

Background: McCune–Albright Syndrome is a combination of polyostotic fibrous dysplasia (BFD), café’-au-lait skin pigmentation and hyperfunctioning endocrinopathies. It results from postzygotic mutations in a-subunit of the Gsalfa protein and the consequent phenotype is a mosaic with high degree of clinical variability.Objective and hypotheses: The aim of the study is determine prevalence and characteristics of GH hypersecretion (GHH) in MA...

Screening of Mutations in Idiopathic Hypogonadotropic Hypogonadism Using a Targeted Next-Generation Sequencing Approach

Kolodkina Anna , Kareva Maria , Kalinchenko Natalia , Raygorodskaya Nadezhda , Malievsky Oleg , Fidelina Olga , Vasilyev Evgeny , Petrov Vasily , Naumova Maria , Tiulpakov Anatoly

Background: To date at least 30 genes are known to be associated with idiopathic hypogonadotropic hypogonadism (IHH). Analysis of all these gene candidates by Sanger sequencing would be expensive, labour-intensive and time-consuming. Recent introduction of next-generation sequencing (NGS) enables simultaneous analysis of multiple gene targets making it an attractive approach in such conditions as IHHObjective and hypotheses: To study the spectrum of mole...

A Case of Autoimmune Polyglandular Syndrome Type I Presenting as Progressive Generalised Lipodystrophy in a 15-month-old Child

Sorkina Ekaterina , Frolova Elena , Rusinova Dina , Polyakova Svetlana , Vasilyev Evgeny , Petrov Vasily , Tiulpakov Anatoly

Background: Autoimmune polyglandular syndrome type 1 (APS1) is a monogenic autoimmune disease caused by defects in autoimmune regulator gene (AIRE). The classic clinical triad is composed of Addison disease, hypoparathyroidism, and chronic mucocutaneous candidiasis, however other endocrine and non-endocrine features of APS1 may occur.Objective: To describe an unusual clinical manifestation of APS1.Methods: Congenital lipodystrophy ...

Late Diagnosis of Adrenal Insufficiency Caused by Novel Compound Heterozygous Mutations in Proopiomelanocortin

Frolova Elena , Shirokova Irina , Karpova Svetlana , Kolodkina Anna , Makretskaya Nina , Tiulpakov Anatoly

Background: Proopiomelanocortin (POMC) deficiency is characterised clinically by adrenal insufficiency, obesity and red hair. As a rule, such patients present early in life with severe hypoglycemia, which leads to initiation of glucocorticoid therapy. We describe here a case of POMC deficiency, where adrenal insufficiency was not diagnosed until the fourth year of life.Objective and hypotheses: To present a case of late diagnosis of POMC deficiency and c...

The Spectrum of Molecular Defects in 64 Patients with Hypophosphatemic Rickets Identified by Targeted Next-Generation Sequencing

Kulikova Kristina , Kolodkina Anna , Vasilyev Evgeny , Petrov Vasily , Gofman Fedor , Horkin Anatoly , Kenis Vladimir , Petrov Michael , Tiulpakov Anatoly

Background: Hypophosphatemic rickets (HR) comprises a group of inherited forms of rickets characterised by renal phosphate wasting. To date more than 10 genes are associated with HR, and a comprehensive molecular diagnosis in these disorders is technically difficult to perform.Objective and hypotheses: To assess the value of targeted next-generation sequencing (NGS) used for molecular analysis of candidate genes of HR.Method: 64 pa...

The Prevalence of Different Subtypes of Maturity-Onset Diabetes of the Young in Russian Federation as Defined by Targeted Next-Generation Sequencing

Zubkova Natalya , Gioeva Olesya , Tichonovich Yulia , Petrov Vasily , Vasilyev Evgeny , Malievsky Oleg , Kiyaev Alexey , Timofeev Alexey , Tiulpakov Anatoly

Background: Among the currently known variants of maturity-onset diabetes of the young (MODY) subtypes 1–3 are the most prevalent, while their relative frequencies vary in different populations. Other types of MODY are more rare, although the studies addressing their prevalences are limited. Recent implementation of next-generation sequencing (NGS) enables simultaneos analysis of multiple candidate genes making it an attracive approach in various monogenic disorders, incl...

Background: Paragangliomas are exceptionally rare neuroendocrine tumours for children and adolescents, located in an extraadrenal position and usually producing catecholamine.Case presentation: A 13.5-year-old girl with a known history of multiple exostosis disease was presented for investigation of two large nodal oval para-aortic lesions, which were incidentally found during abdominal ultrasonography. Medical history of the girl included non-autoimmune...
