Kungurtseva Anastasiia , Tikhonovich Yulia , Popovich Anastasiia , Vitebskaya Alisa

Introduction: Wiedemann-Rautenstrauch syndrome (WRS). or neonatal progeroid syndrome, is an orphan hereditary disease associated predominantly with bi-allelic mutations in the POLR3A, POLR3B, and POLR3GL genes and characterized by congenital lipodystrophy, progeroid facial features, and premature aging. Unlike Hutchinson-Gilford progeria, the clinical features of the syndrome are evident at birth. The prevalence of the disease is unknown; 19 proven clinical ca...

Introduction: The PLIN1 gene encodes perilipin - a lipid droplet coat protein expressed in adipocytes where it inhibits basal and facilitates stimulated lipolysis. Mutations in PLIN1 have been described in several families with partial lipodystrophy, dyslipidemia and insulin resistance (partial lipodystrophy type 4, Familial, FPLD4). Herein we describe a novel heterozygous c.1210-1delG splicing variant in PLIN1 gene in three unrelate...

Successful Transition to Sulfonylurea Therapy in Infant with Neonatal Diabetes, Developmental Delay, Epilepsy (DEND Syndrome) due to F132L ABCC8 Mutation

Introduction: The heterozygous activating mutations in the KCNJ11 and ABCC8 are the commonest causes of permanent neonatal diabetes mellitus (PNDM). The most severe clinical form of NDM is DEND syndrome. Besides diabetes mellitus such patients show severe developmental delay, hypotonia and therapy-resistant epilepsy. To our knowledge only some cases of DEND syndrome due to ABCC8 mutations are sulfonylurea-responsive. Here we report case of DEND syndrome due t...

Insulin-dependent diabetes mellitus in a young child in the structure of monogenic immune dysregulation syndrome (LRBA deficiency)

Tikhonovich Yulia , Petryaikina Elena , Vorontsova Inna , Putilina Ekaterina , Kondratenko Irina , Tyulpakov Anatoly

Objectives: Diabetes mellitus (DM) as part of autoimmune dysregulation syndromes holds a unique place among DM monogenic forms. Early diagnosis of the disease is critical for pathogenetic therapy to be prescribed. We describe a clinical case of insulin-dependent DM in combination with severe autoimmune enteropathy in a young patient who had a novel compound heterozygous mutation in the LRBA gene.Methods: The patient unde...
